Question

Define the unit of current.

Answer 1

The unit of electric current is ampere (A). 1 A is defined as the flow of 1 C of charge through a wire in 1 s.

Answer 2

The unit of electric current is ampere (A). When 1 C of charge flows through a conductor in 1 s, it called 1 ampere (A) current.
I =Q/t

Answer 3

The SI unit of the electric current is ampere (A). The current flowing through a conductor is said to be one ampere when a charge of one coulomb flows across any cross-section of a conductor in one second. Hence,
1 ampere = \(\frac{1 \text { coulomb }}{1 \text { second }}\).
