WebPotential differences (voltage) The potential difference (or voltage) of a supply is a measure of the energy given to the charge carriers in a circuit. Part of. Physics. Electricity. WebIn a series. circuit, the total resistance across all of the components (the 'net resistance') increases as more components are added. The two resistors have the same current through them. The potential difference across them will be different if they have different resistances. The total resistance (\(R_{T}\)) for this circuit is \(R_{1} + R ...
