One coulomb of charge flows through a cross-section of a wire every second. What is the current in the wire?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 1 ampere
Electric current is the rate of flow of charge, I = Q/t. A flow of 1 coulomb per second is a current of 1 ampere (1 A = 1 C/s).
