Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. It is measured in volts and is also called voltage. Learn how to calculate and measure potential difference with examples and diagrams.
The electric potential difference between points A and B, \ (V_B - V_A\) is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. \ [1 \, V = 1 \, J/C \label {eq0}\]
Learn what potential difference (voltage) is and how it is measured in a circuit. Find out how a battery produces an electric field and transfers energy to charge carriers and components.
The difference between potential difference and e.m.f is the type of energy transfer per unit charge. When charge passes through a resistor, for example, its electrical energy is converted to heat in the resistor. The resistor, therefore, has a potential difference across it.
