Question

the amount of current passed through a conductor if 90 coulomb of charge flows in 1 min​

Answer 1

Given :

Charge flow through a conductor in 1 minute is 90 coulomb.

To Find :

Current passing through conductor.

Solution :

❖ Electric current is defined as the rate of charge flow through conductor per unit time.

Mathematically, I = Q / t

» I denotes current

» Q denotes charge

» t denotes time

• Electric current is a scalar quantity having only magnitude.
• SI unit : A (ampere)
• SI unit : [M⁰L⁰T⁰A¹]

First of all we need to convert unit of time into second$.$

We know that, 1 min = 60 s

By substituting the given values;

➙ I = Q / t

➙ I = 90/60

➙ I = 9/6

➙ I = 3/2

➙ I = 1.5 A
