Application +4 | -1

The current in a conductor varies with time

t

I = 2t + \,\,3{t^2}

where

I

is in ampere and

t

in seconds. Electric charge flowing through a section of the conductor during

t = 2\,\,\sec

t = 3\,\,\sec

View answer and explanation

Correct option: B

24\,\,C

Option B (

24 \mathrm{~C}

) is correct because the total charge is the integral of the current with respect to time from t=2 to t=3.
