Sample practice questions
Easy
1. What is the SI unit of current?
Ampere (A)
Volt (V)
Ohm
Coulomb (C)
Answer: Ampere (A) — Current is measured in ampere (A), which is the same as coulomb per second.
Easy
2. How is current defined?
The rate of flow of charge
The total charge in a circuit
The opposition to the flow of charge
The energy stored in a cell
Answer: The rate of flow of charge — Current, I, is defined as the rate of flow of charge, measured in ampere (A).
Medium
3. Calculate the current, in A, when 15 coulombs of charge flow past a point in a circuit in 3 seconds.
