WebThe current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. WebApr 5, 2024 · The difference in electric potential energy (per charge) between two points is what we have given the name voltage. Thus, the voltage directly tells us which way charges want to move - and if they can, then they will speed up in that direction, so the current will increase. This is Ohm's law.
