✔ 最佳答案
A RC circuit c= 20pf, R=10M ohms Time Constant=? Time Constant = CR = ( 20 / 1000000000000 ) x ( 10 x 1000000)= 200 / 1000000 = 0.2 / 1000 = 0.2(mS) An inductor with 5 ohm and 12uH is applying a current with 5A and 50Hz.Calculate the power in the inductor.P = I V = I ( I r ) = 5( 5 x5) = 125(W)
