Charge through a cross-section of a conductor is given by Q = 5t^2 - 2...
Q(t) = 5t^2 - 2t We have to find out current in time interval 2 to 4 sec So, use formula , i = [Q(t2) - Q(t1) ]/(t2 - t1) Q(t2) = Q(4) = 5(4)^2 - 2(4) = 80 - 8 = 72 Q(t1) = Q(2) = 5(2)^2 - 2(2) = 20 - 4 = 16 so, current , i = (72 - 16)/(4 - 2) = 56/2 = 28 Ampere .Hence, current through the conductor in 2 to 4 sec is 28 Amperes.

I=q2-q1/t2-t1I={5×16-8} - {5×4-4}/{4-2}I ={72-16}/2I =56/2I =28A
