## 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 …

## Parallel Combination of Resistances or Parallel Resistances

In the parallel combination of resistances, we connect more than one resistance.  here, we connect more than one resistor in a certain manner.  We connect one end of all the resistors to a common node. …

## 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 …

## 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 the opposite property of resistance. Because …

## Resistance Definition and Units of Electrical Resistance

The electrical resistance is a property of a piece of substances. Let us apply an electric potential difference between two points in a substance. As a result, there is an electric current. This current will …

## Resistivity and Laws of Resistance and Unit of Resistivity

Hi friends, this post is about the laws of resistance and resistivity. Laws of Resistance A conductor is anything that can conduct electricity. Every conductor offers certain resistance to the electric current through it. This …

## Norton’s Theorem – Norton’s Current and Resistance

Definition of Norton’s Theorem As per Norton’s theorem, we can replace a complex linear active two-port network with a single current source in parallel with a resistance. The next question comes to our mind what …

## Thevenin’s Theorem Thevenin’s Voltage and Resistance

Thevenin’s Theorem is a process of circuit analysis. It converts a comparatively complicated active circuit to a simplified form. According to Thevenin’s Theorem, we can consider an entire two-port circuit network as an ideal voltage …

## Kirchhoff’s Current Law and Kirchhoff’s Voltage Law

There are two numbers of Kirchhoff’s laws. These laws are Kirchhoff’s Current Law and Kirchhoff’s Voltage Law. We use very frequently these laws in circuit analysis. The famous German Physicist Gustav Robert Kirchhoff (1824 – …
