What is the unit of electric current?

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

Answer: (C)

The unit of electric current is called the Ampere, often abbreviated as "A." The Ampere defines the flow of electric charge in a circuit, specifically representing one coulomb of charge passing through a conductor in one second. This unit is crucial in understanding electric circuits and their behavior since it quantifies the amount of electric charge flowing over time.

In contrast, other units mentioned relate to different electrical concepts. Watt measures power, which is the rate of energy transfer, volt refers to electric potential difference, and ohm signifies electrical resistance. Each of these has its specific role in the study of electricity, but they do not define the flow of current itself. Therefore, the Ampere is the correct answer as it directly pertains to measuring electric current in a circuit.
