Question

Write the S.I. unit of :
(i) Electric current.
(ii) Electric charge

Answer 1

Explanation:

the si unit of electric current is ampere

the si unit of electric charge is coulomb

Answer 2

Electric current - Ampere

Electric charge - Coulomb

Explanation:

The SI unit of electric current is Ampere (symbol: A).  1 ampere is the constant current that will produce an attractive force of 2 × 10−7 Newton per meter of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one meter apart in a vacuum.

The SI unit of electric charge is coulomb (symbol: C). One coulomb is the amount of charge in one ampere-second.
