Calculate the current supplied by a cell if the
amount of charge passing through the cell
in 2 minutes is 240 c?​

Answer 1

Answer:

i=q/t

Explanation:

i=240/(2x60)=2A

Answer 2

Given :

Charge flow = 240C

Time interval = 2min

To Find :

Current supplied by cell..

Solution :

★ Electric current is defined as the rate of charge flow per unit time in the conductor.

Mathematically, [I = Q / t]

I denotes current

Q denotes charge

t denotes time

It is a scalar quantity having only magnitude.

SI unit : A (ampere)

★ Conversion :

We know that 1min = 60s

∴ 2 min = 2 × 60 = 120s

By substituting the given values;

➠ I = Q / t

➠ I = 240/120

➠ I = 2A
