This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference change: ...

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...

The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...
