Question: 1 / 400

What is the unit for voltage (V)?

Ohms (Ω)

Coulomb (C)

Amps (A)

Volts (V)

The unit for voltage is volts, designated by the symbol "V." Voltage is a measure of the electric potential difference between two points in a circuit. It quantifies the amount of work needed to move a charge from one point to another, essentially reflecting the "pressure" that pushes electric charge through a circuit.

In understanding the other choices: ohms (Ω) is the unit for resistance, which measures how much a material opposes the flow of electric current. Coulombs (C) represent the unit of electric charge, describing the quantity of electricity. Amps (A), or amperes, measure the flow of electric current, specifically the rate at which charge is flowing through a conductor. Each of these units is integral to the study of electricity, but only volts specifically denotes the voltage itself.
