The current in a conductor varies with time

t

as

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

to

t = 3\,\,\sec

is

View answer and explanation

Correct option: B

24\,\,C

Option B (

24 \,C

) is correct because it is the total charge calculated by integrating the current function with respect to time from 2 to 3 seconds.
