Question

What is Power Dissipated in Moving the Conductor?

Answer

Power Dissipated in Moving the Conductor - For uniform motion of rod PQ, power delivered by external source is given as P_mech = P_ext = dW/dt = F_ext×v = B²vl²/R×v ⇒ [P_mech = B² v² l²/R Also, electrical power dissipated in resistance or rate of heat dissipation across resistance is given as P_thermal = H/t = I² R = (Bvl/R)²×R; P_thermal = B² v² l²/R
