4 µJ The switch in Figure P32.52 is connected to point a for along time (C = 1.40 mu F).Suppose that the switch is thrown to point b. Figure P32.52 (a) What is the frequency of oscillation of the LC circuit? 1 Hz (b) Determine the maximum charge that appears on the capacitor. 2 mu C (c) Determine the maximum current in the inductor. 3 mA (d) Determine the total energy the circuit possesses at t= 3.00 s. 4 mu J
Explanation / Answer
a) the frequency of oscillation is f =1/2*LC = 1/2*{(0.01H)*(1.40*10-6F)} = --------- b) when the switch is moved to position b at t=0 , as thecpacitor as open ckt, voltage Vmax = 12V maximum charge on the capacitor Qmax =CVmax Qmax = (1.40*10-6F)12V c) maximum current through inductor Imax =Qmax = 2fQmax d) the total energy is independent of time so, U =1/2*LImax2 = 1/2*(0.10H)*Imax2 = ------------ = ------------Related Questions
