Question

A current of 0.4a is flowing through a bulb for 3 minutes. find the charge that is flowing through the circuit

Answer 1

Answer:

Explanation:

Current= I = 0.4 amphere

Time =t= 3 minutes

FORMULA

                  Charge= It

                               =0.4*3

                               =1.2   Ans

Answer 2

Answer:

$72$ $C$ is the charge that is flowing through the circuit for 3 minutes.

Explanation:

Given: Current, $I=0.4$ $A$

Time, $T=3$ minutes

             $=3$ × $60$

             $=180$ seconds

We know that,

Electric charge = Electric current × Time

i.e., $Q=I$ × $T$ ...... (1)

Substitute the values $0.4$ for $I$ and $180$ for $T$ in the equation (1) as follows:

$Q=0.4$ × $180$

   $=72$ $C$

Therefore, the charge that is flowing through the circuit for 3 minutes is $72$ $C$.
