What is the standard unit of electric current?

• A. Joules
• B. Amps
• C. Volts
• D. Ohms

Answer: (B)

The main idea is identifying the unit that measures how much electric charge passes a point in a given time. That unit is the ampere, abbreviated A. An ampere represents one coulomb of charge moving past a point every second, so if one coulomb flows each second, the current is one ampere. The other terms refer to different quantities: joules measure energy, volts measure electric potential difference, and ohms measure resistance. In practical terms, currents in circuits are often expressed in amperes or fractions like milliamperes, while the ampere is the standard for current.
