Question

The unit of electrical current is the ampere (A).
Which one of the combinations of units below is equivalent to the ampere?

A) C·s

B) C/s

C) N·m/s

D) J·s

E) kg·m²/s

Answer 1

Answer:

option B

Explanation:

Current unit is ampere (A)

Ampere will be equivalent to = ?

we know,

Current can be define as the charge per unit time

$I = \dfrac{Q}{t}$

unit of charge(Q) is coulomb which is equal to C.

unit of time(t) is equal to 's'.

now,

$I = \dfrac{C}{s}$

unit of I = C/s

ampere(A) is equivalent to C/s

The correct answer is option B
