Question

For how long 2.5 ampere of current is passed to supply 5400c of charge

Answer 1

We know that,

Amount of chanrge flown per unit time is called Current.

so,

according to this,

$\bold{Current,(I)=\frac{Charge,(Q)}{Time,(t)}}$

It is given that,

I = 2.5 A

Q = 5400 C

Therefore,

time, t= $\frac{Q}{I}$

=> t = $\frac{5400}{2.5}$

=> t = 2160 s

Hence,

time taken to flow the charge =

$\bold{2160\:seconds}$

Answer 2

The time for which current passes is 0.6 hours

Explanation:

Given that,

Current, I = 2.5 A

Charge, q = 5400 C

We need to find the time for which current passes. Electric current is defined as the net charge flowing per unit time. It is given by :

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

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

$t=\dfrac{5400\ C}{2.5\ A}$

t = 2160 seconds

or

t = 0.6 hours

So, the time for which current passes is 0.6 hours. Hence, this is the required solution.
