Ampere is the unit of measure for electrical current.

• A. Watt
• B. Volt
• C. Ampere
• D. Ohm

Answer: (C)

Current is the rate at which electric charge flows through a conductor. The ampere is the unit that measures that flow, defined as one coulomb of charge passing a point each second. In circuits you’ll see current labeled in amperes (A), and an ammeter is used to measure this quantity. The other units describe related quantities but not current itself: the volt measures electrical potential difference (the push that drives current), the ohm measures resistance (how much a material resists current), and the watt measures power (the rate of energy transfer, linked to current by P = VI or P = I^2R). So ampere is the unit specifically for current.
