Question

The current flowing through wire depends on time as, 1 = 3t^(2) + 2t + 5The charge flowing through the cross - section of the wire in time t = 0 to t = 2 second is

Answer 1

Explanation:

As I=Q÷t

Integration of current with respect to time gives charge

so

integrating above equation we get

I=t^3 + t^2 +5t

applying the limits 0 and 2

I=8+4+10

I=22C
