Which term describes the basic unit of electrical charge?

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

Answer: (A)

Charge is quantified using the coulomb. A coulomb is defined as the amount of charge transferred by a current of one ampere in one second, linking how much charge moves to the time and current involved. This distinguishes it from the other terms: an ampere is the rate at which charge flows (current), a volt is the electric potential difference (energy per charge), and an ohm is the unit of electrical resistance. So, for the basic unit that measures how much electric charge there is or moves, the coulomb is the correct term.
