Question

A current of 4.0 ampere is drawn by an electric bulb for 20 minutes find the amount of electric charge that flows to the electric circuit

Answer 1

$\boxed{\textbf{\large{Explanation:}}}$

current = charge / time

I = Q / t

Q stands for charge, I = current,

t =time

▶here we have given , current and time we have to find charge that flowing in an electric circuit .

I ( current) = 4.0 ampere

time ( t) = 20 minutes = 20 x 60 = 1200 sec

therefor, I = Q / t

Q = I x t

Q = 1200 x 4

Q= 4800C

Amount of electric charge that flows to the electric circuit is 4800C.

Answer 2

Answer :-

Q = 4800 C

Given :-

Electric current drawn(I) = 4A

Time = 20 minutes

Change in to second = 20 × 60 = 1200 s

To find :-

The amount of charge flows to the circuit.

Solution:-

As we know the charge , current and time is related by the formula :-

I = Q / T

Where I is current

Q is charge

T is time

Now,

$Q = {I}{T}$

$Q = 4 . 1200$

$Q = 4800 Columb$

hence,charge flow to the electric current is 4800 C.
