The voltage across the ends of the cell is called the terminal potential difference, \(V_{tpd}\). \(V_{tpd}\) can also be calculated as \(I R\) where \(R\) is the load resistance. Voltage is a ...

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 ...
