## Current Electricity Formulas

An electric current is the rate of flow of charged particles, such as electrons or ions, through an electrical conductor or space. It is measured in Coulombs/second which is named …

## Dimensions of Resistance

Resistance is a measure of the opposition to the flow of electrons and is calculated by dividing voltage upon current in the conductor. The dimensions of resistance can be given …

## Fleming Left Hand Rule

Fleming Left Hand Rule is used when a current-carrying conductor is placed in an external magnetic field wherein it experiences a force perpendicular to both the magnetic field and the …

## Carbon Resistor

The carbon resistor is the most common form of resistor used in electronics. They are made of a sturdy cylindrical resistive element with embedded wire leads or metal end caps. …

## Equipotential Surface

A surface having the same potential at every point is referred to as an equipotential surface. There is no work done in order to move a charge from point A …

## Ohm’s Law

Ohm’s Law is an empiric relation, accurately describing the conductivity of a material. It defines the relationship between the electric current passing through a circuit and the potential difference between …

## Wheatstone Bridge

A Wheatstone Bridge is an electrical circuit used to measure an unknown resistance by balancing two legs(one leg containing the unknown component) of the circuit. History The Wheatstone bridge was …

## Ampere’s Law

Ampere’s Law is an integral part of the concept of electromagnetism and is also known as Ampère’s circuital law. Ampère’s law is an alternative expression of Biot Savart Law. History …

## Biot Savart Law

Biot Savart Law is basically an equation describing the magnetic field generated by a constant electric current.  It establishes a relationship between the magnetic field and the magnitude, direction, length, …
