The unit for electric current is?

The unit for electric current is?

• A. Volts
• B. Ohms
• C. Amperes or coulombs per second
• D. Watts

Answer: (C)

Electric current is the rate at which electric charge flows through a point in a conductor. The SI unit for this flow is the ampere, defined as one coulomb passing per second. So using amperes or coulombs per second describes the same quantity. In practice, current tells us how much charge moves each second, and it’s what an ammeter measures in a circuit. The other terms refer to different quantities: volts are the push or potential difference that drives charges, ohms quantify how much a material resists the flow, and watts represent power, or energy transfer per second. Ohm’s law ties them together as I = V/R, showing how current depends on voltage and resistance.
