The charge flowing through a resistance R varies with time t as Q = at - bt^(2) . The total heat produced in R is

The charge flowing through a resistance R varies with time t as Q = at - bt^(2) . The total heat produced in R is

The charge flowing through a resistance R varies with time as Q=2t-8t^(2) . The total heat produced in the resistance is (for 0letle(1)/(8))

The charge flowing in a conductor varies with time as Q ="at"- (1)/(2)bt^(2)+(1)/(6)ct^(3) , where a,b,c are positive constant. Then, the current i = (dQ)/(dt)

The charger Q(in coulomb) flowing through a resistance (R = 10Omega) varies with time t(in second) as (Q= 2t- t overset2 ). The total heat produced in resistance R is
