Question
A time varying i is speed through a resistance R as shown in figure. The total generated in the resistance is
Options
A.11i02Rt0
B.13i02Rt0
C.17i02Rt0
D.15i02Rt0
Solution
Total heat produced = 
Rdt + (3i0)2 R(2t0 - t0) + i02R(3t0 - 2t0) = 3i02Rt0 + 9i02Rt0 + i02Rt0 = 13iRt0
Rdt + (3i0)2 R(2t0 - t0) + i02R(3t0 - 2t0) = 3i02Rt0 + 9i02Rt0 + i02Rt0 = 13iRt0Create a free account to view solution
