One volt is the potential distinction between two factors in a circuit that requires one joule of labor to maneuver one coulomb of cost from one level to the opposite.
V = W/q
the place V is the potential distinction, W is the work carried out, and q is the cost moved.
Evaluating Electrical Potential Between Two Factors in a Circuit
The electrical potential at two factors in a circuit can differ considerably, relying on the configuration of the circuit and the presence of resistance. Generally, the electrical potential at a degree in a circuit is influenced by the voltage sources and conductors linked to it.
The desk beneath exhibits a comparability of electrical potential at two factors in a easy circuit with a battery and a resistor:
| Level | Electrical Potential (V) | Remark |
| — | — | — |
| A (constructive terminal of battery) | 10 V | Reference level with most electrical potential |
| B (damaging terminal of battery) | 0 V | Minimal electrical potential, with zero potential distinction |
| C (junction of battery and resistor) | 8 V | Diminished electrical potential attributable to resistance and present circulate |
| D (far finish of the resistor) | 8 V | Identical electrical potential as level C, with no internet potential distinction |
Observe: The precise values of electrical potential at factors A, B, C, and D will depend upon the particular circuit configuration and the voltage supply used.
