Question

The current through a wire depends on time as I = 3t2 + 2t + 5 the charge flowing through the cross section of the wire in time from t=o to t=2s if

Answer 1

Answer:

22 columb

Explanation:

Q=i.dt

Intergrating current wrt time gives me the folllowing equation

t^3+t^2+5t apply the limit

lower limit is 0 and upper limit is 2

Ans comes out to be 8+4+10=22 unit charge
