Green's Theorem

In mathematics, Green's theorem gives the relationship between a line integral around a simple closed curve C and a double integral over the plane region D bounded by C. It is the two-dimensional special case of the more general Stokes' theorem, and is named after British mathematician George Green.

Let C be a positively oriented, piecewise smooth, simple closed curve in the plane ², and let D be the region bounded by C. If L and M are functions of (x, y) defined on an open region containing D and have continuous partial derivatives there, then

For positive orientation, an arrow pointing in the counterclockwise direction may be drawn in the small circle in the integral symbol.

In physics, Green's theorem is mostly used to solve two-dimensional flow integrals, stating that the sum of fluid outflows at any point inside a volume is equal to the total outflow summed about an enclosing area. In plane geometry, and in particular, area surveying, Green's theorem can be used to determine the area and centroid of plane figures solely by integrating over the perimeter.

Vector Integration: Line Integral

In mathematics, a line integral (sometimes called a path integral, contour integral, or curve integral; not to be confused with calculating arc length using integration) is an integral where the function to be integrated is evaluated along a curve.

The function to be integrated may be a scalar field or a vector field. The value of the line integral is the sum of values of the field at all points on the curve, weighted by some scalar function on the curve (commonly arc length or, for a vector field, the scalar product of the vector field with a differential vector in the curve). This weighing distinguishes the line integral from simpler integrals defined on intervals. Many simple formulae in physics (for example,W=F·s) have natural continuous analogs in terms of line integrals (W=∫_C F· ds). The line integral finds the work done on an object moving through an electric or gravitational field, for example.

Equilibrium of Concurrent and Coplanar Force System

The conditions of equilibrium for concurrent force systems are obtained by determining the equations that produce a zero resultant. The magnitude of the resultant of a concurrent force system is found by means of the equation:

Obviously, the resultant will be zero and equilibrium will exist when the following equations are satisfied:

These equations are known as the conditions of equilibrium. It is important to note that with two conditions of equilibrium, only two unknown quantities can be determined to create equilibrium of a concurrent force system. (from Engineering Mechanics, 2nd edition by Ferdinand Singer)

The presentation file below gives a thorough discussion on equilibrium of concurrent and coplanar force systems:

Superposition

Superposition is a good method to apply in analyzing circuits with multiple sources. The basic concept of this method is to analyze a circuit one source at a time. Using the Superposition Theorem, we remove all the independent sources, except one, and analyze that circuit for that one. Then we repeat the procedure for another source, and so on. Finally, the net result is found by summing all the single -source results. 

'Removing' Power Sources

If we have two voltage sources and we were to remove one source, and still have a complete circuit, we must replace the voltage source with a short circuit.

Source Transformation

In order to solve difficult and complicated circuits, it is important to simplify the given circuit for easier analysis. One way to simplify circuits is by Source Transformation. It is the process of using Ohm's Law to take an existing voltage source in series with a resistance, and replace it with a current source in parallel with the same resistance or vice-versa. This method can be applied to Thevenin's theorem and Norton's theorem.

Vector Differentiation

In calculus we compute derivatives of real functions of a real variable. In the case of functions of a single variable

            y = f(x)

we compute the derivative of y with respect to x. In the case of a function of several variables

            y = f(x₁, x₂, ... , x_n)

we can compute the derivative of y with respect to any one of the independent variables, viewing the others as fixed.

In vector analysis we compute derivatives of vector functions of a real variable; that is we compute derivatives of functions of the type

            F(t) = f₁(t) i + f₂(t) j + f₃(t) k

This function can be viewed as describing a space curve. Intuitively it can be regarded as a position vector, expressed as a function of t, that traces out a space curve with increasing values of t. Expressed in different notation it is the function
      R(t) = x(t) i + y(t) j + z(t) k

Bipolar Junction Transistor

The bipolar junction transistor (BJT) is a three-element (emitter, base, and collector) device made up of alternating layers of n- and p-type semiconductor materials joined metallurgically. The transistor can be of pnp type (principal conduction by positive holes) or of npn type (principal conduction by negative electrons), as shown in Fig. 3-1 (where schematic symbols and positive current directions are also shown). The double subscript notation is utilized in labeling terminal voltages, so that, for example, Vbe symbolizes the increase in potential from emitter terminal E to base terminal B. For reasons that will become apparent, terminal currents and voltages commonly consist of superimposed dc and ac components (usually sinusoidal signals).

Diode Applications: Clamping Circuits

A clamper is a circuit that is designed to shift a waveform above or below a dc reference voltage without altering the shape of the waveform. This results in a change in the dc average of the waveform.

Both of these statements are illustrated in the figure below. (The clamper has changed the dc average of the input waveform from 0 V to +5 V without altering its shape.)

A clamper with its input and (ideal) output waveforms.

Diode Applications: Clipping Circuits

Clippers or Diode Limiters are networks that employ diodes to "clip" away a portion of an input signal without distorting the remaining part of the applied waveform. For a clipping circuit at least two components—an ideal diode and resistor are required and sometimes a dc battery is also employed for fixing the clipping level. The diode acts as a closed switch when forward biased and an open switch when reverse biased. The input waveform can be clipped at different levels by simply changing the voltage of the battery and by interchanging the positions of the various elements.

Venn There, Done That

A Venn Diagram is a picture that is used to illustrate intersections, unions, and other operations on sets.

The Venn diagrams on two and three sets are illustrated above. The order-two diagram (left) consists of two intersecting circles, producing a total of four regions, , , , and  (the empty set, represented by none of the regions occupied). Here, denotes the intersection of sets  and .

Philippine Republic Act 9292: ECE Law

The Republic Act 9292 or the "Electronics Engineering Act of 2004” is an amendment of the previous RA 5734.  The new law has brought about debates from ECE students and professionals from the Electronics industry.

There were few major changes made on the law, such as the new board exam rules and the classifications of e licensed to Electronics Engineers (ECT, ECE and PECE).

Electronics and Communications Engineering would now be called Electronics Engineering. However, Communications would still be part of the ECE curriculum. Also, you need to pass the licensure exam first before you can affix the ECE title on your name.

PRC List of Allowed Calculators

Examinees are allowed to bring only one non-programmable calculators during the board exam.

Is your calculator allowed?

Here is the complete and updated list of allowed calculators to be used in Licensure Examinations, according to the Professional Regulation Commission.

Applications of Differential Equations

What's the use of learning to solve differential equations if you don't know how to apply it to real-life situations?

Differential equations arise in many areas of science and technology. This lecture will show examples where differential equations can be widely applied to model natural phenomena, engineering systems and many other situations.

Newton's Law of Cooling

Wye-Delta Conversion

In many circuits, resistors are neither in series nor in parallel, so the rules for series or parallel circuits described in previous chapters cannot be applied. For these circuits, it may be necessary to convert from one circuit form to another to simplify the solution. Two typical circuit configurations that often have these difficulties are the wye (Y) and delta (D) circuits.

Wye to Delta

Vector Multiplication: Cross Product

We define the cross product of two three-dimensional vectors a and b by the requirements:

• a × b is a vector that is perpendicular to both a and b.
• ||a × b|| is the area of the parallelogram spanned by a and b (i.e. the parallelogram whose adjacent sides are the vectors a and b).
• The direction of a×b is determined by the right-hand rule. (This means that if we curl the fingers of the right hand from a to b, then the thumb points in the direction of a × b.)

Vector Multiplication: Dot Product

The multiplication of two vectors, is not uniquely defined, in the sense that there is a question as to whether the product will be a vector or not. For this reason there are two types of vector multiplication.
First, the scalar or dot product of two vectors, which results in a scalar.
And secondly, the vector or cross product of two vectors, which results in a vector.

In this tutorial we shall discuss only the scalar or dot product.

How to Use an Oscilloscope

The oscilloscope is a particularly useful item of test equipment that can be used for testing and fault-finding a variety of electronics circuits from logic circuits through analogue circuits to radio circuits. It is necessary to know how to use an oscilloscope properly to be able to make the best use of it. By knowing the basics of using an oscilloscope it is possible to fault find circuits more effectively and more swiftly as well as gaining a better understanding of how they the circuits work.

Introduction to Electronics: Terminology

This article contains the terms that we will often encounter in the succeeding lessons in Electronics.

AC and DC

Electricity flows in two ways, either in alternating current (AC) or in direct current (DC). The difference between AC and DC has to do with the direction in which the electrons flow.

In DC, the electrons flow steadily in a single direction, or "forward." In AC, electrons keep switching directions, sometimes going "forwards" and then going "backwards." DC is the kind of electricity generated by a battery. On the other hand, the power that comes from wall outlets is AC.

AC can even be changed to DC by an adapter, such as that used to power the battery on a laptop.
