Single Device in AC Circuit: Application (2) Consider an ac generator E ( t ) = E max cos( ωt ) , E max = 25 V, ω = 377 rad/s connected to an inductor with inductance L = 12 . 7 H. (a) Find the maximum value of the current. (b) Find the current when the emf is zero and decreasing. (c) Find the current when the emf is - 12 . 5 V and decreasing. (d) Find the power supplied by the generator at the instant described in (c).
