In Ohm's Law, V stands for what?

Explanation:
Voltage is the electrical potential difference—the push that moves charges through a circuit. In Ohm's Law, it’s the symbol V, and it relates to current and resistance by V = I R. Voltage is measured in volts (V), a unit named after Alessandro Volta. If you raise the voltage while resistance stays the same, current increases; if you raise resistance at a fixed voltage, current decreases. The other quantities—current (I), resistance (R), and power (P)—have different meanings and units, so the symbol V specifically represents voltage.
