What is the basic unit of electrical quantity?

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

Answer: (A)

Charge is the fundamental electrical quantity being measured. The basic unit for electric charge is the coulomb, defined as the amount of charge transferred by a constant current of one ampere in one second. In other words, one coulomb equals one ampere-second. This unit specifically counts how much electric charge an object has, whereas the ampere measures how fast charge moves (current), the volt measures potential difference or electrical pressure, and the ohm measures how strongly a material resists the flow of charge.
