The symbol V is used to represent which quantity in electricity?

V represents voltage, the electric potential difference between two points in a circuit. Voltage is what pushes charges to move, creating current. The symbol for current is I, for resistance is R, and for power is P, so V is specifically the quantity of voltage. The volt is the unit, defined as one joule per coulomb. For example, a 9 V battery provides a 9-volt potential difference that can drive current through a circuit. Ohm’s law links these ideas with V = I R and power with P = V I, showing how voltage relates to current, resistance, and power.
