In Ohm's Law, which quantity represents voltage?

Explanation:
Voltage is the electrical potential difference that pushes charges to move through a circuit. In Ohm's Law, the letters represent V for voltage, I for current, and R for resistance, with the relationship V = I R. Voltage is what creates the “pressure” that drives current, and it's measured in volts. Current is the actual flow of electrons, measured in amperes, while resistance is the opposition to that flow, measured in ohms. Power is the rate of energy transfer, related by P = V I, which explains why it’s not the driving force represented by voltage. So the quantity that represents voltage is the electrical potential difference—the push behind the current.
