57. From Eq. 31-51 and Eq. 31-43, the rate at which the energy is being stored in the inductor is dU B dt = d ( 1 2 Li 2 ) dt = Li di dt = L µ E R ³ 1 e t/τ L ´ ¶µ E R 1 τ L e t/τ L = E 2 R ³ 1 e t/τ L ´ e t/τ L where τ L = L/R has been used. From Eq. 27-22 and Eq. 31-43, the rate at which the resistor is generating thermal energy is P thermal = i 2 R =
