What is the name of the unit measuring electric current?

• A. Volts
• B. Coulombs
• C. Amperes
• D. Ohms

Answer: (C)

The unit measuring electric current is called Amperes. This unit quantifies the flow of electric charge in a circuit. Specifically, one ampere is defined as the flow of one coulomb of charge per second. This is fundamental in understanding how electrical systems operate, as current is a key principle in electrical theory and applications.

Volts measure the electric potential or voltage, which represents the force that drives electric current through a conductor. Coulombs are a unit of electric charge, indicating the amount of charge but not the rate of flow. Ohms measure electrical resistance, which quantifies how much a material opposes the flow of electric current. Understanding the distinction between these units is crucial for anyone studying electrical engineering or working in related fields.
