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 Pmech = Pext = dW/dt = Fext×v = B2vl2/R×v ⇒ [Pmech = B2 v2 l2/R Also, electrical power dissipated in resistance or rate of heat dissipation across resistance is given as Pthermal = H/t = I2 R = (Bvl/R)2×R; Pthermal = B2 v2 l2/R
