## Capacitance – What is Capacitance?

Each capacitor has a special property. Due to this property, a capacitor can store electrical energy. We call the property as the capacitance. Again sometimes, we call the capacitance as the capacity of the capacitor. … Read more

## Compensation Theorem

Before understanding Compensation Theorem, one question that comes in your mind. Why Compensation Theorem? i.e. why do we need this theorem? Compensation Theorem is a useful theorem. We can apply it to directly find the … Read more

## Star Delta Conversion and Delta Star Conversion

Besides the series or parallel connection, we can connect the resistors or other circuit elements also in STAR and DELTA connection. Star to Delta Transformation Let R1 R2 and R3 are three resistors. These resistors … Read more

## Circuit Analysis or Network Analysis

Definition of Circuit Analysis Electrical Circuit Analysis is a process of finding out different unknown parameters of a circuit. Description The parameters are resistance, voltage, current, power, energy, impedance, admittance, inductance, reactance, capacitance, conductance, phase angle and many more. We often have to … Read more

## Resistor Color Coding 3, 4, 5 Band Resistor Color Coding

To identify and select a resistor by its value resistor color coding is necessary. We find resistors in many applications in electrical, electronic and communication industries. Because resistors play a significant role in producing voltages … Read more

## Resistances in Parallel

When more than one resistors are connected in such a manner, that one end of all the resistors are connected to a common node and other end of all resistors are connected to another node. The parallel connection of resistors is … Read more

## Resistances in Series

When a number of resistances are connected in head to tail manner one after another in series is called resistances connected in series or simply resistances in series. We sometimes also call it series resistances.   The equivalent resistance of a series combination of resistances is algebraic sum of all the … Read more

## Conductance and Conductivity

The conductance is a property of a substance due to which it facilitates the flow of current through it when a voltage is applied across the substance. It is a reverse of resistance because the resistance is the property of a substance by … Read more

## Electrical Resistance

Whenever we apply an electric potential difference between two points in a substance there is an electric current flowing through it one point to another. This current may be anything from zero to infinity depending … Read more

## Laws of Resistance and Resistivity

Laws of Resistance A conductor is anything which can conduct electricity. Every conductor offers certain resistance to the electric current through it. This resistance depends on four factors. The length,  cross section, material and temperature. The resistance (R) of a … Read more
