Welcome to this IE. You may navigate to any page you've seen already using the IE lab on the right. A series RLC circuit (L = 340 times 10^-3 H, C - 25 times 10^-6 F, and R = 280 ohms) has an AC generator with amplitude epsilon_max = 120 V and unknown frequency f. At time t - 0. the following voltages are measured: V_ad - V_a - + 120V, V_bc - V_b - V_c = -10.1 v, and V_cd - V_c - V_d = + 60.6 V. What is t_imax, the first time after t = 0 that the current in the circuit attains its maximum value? t_imax =

Explanation / Answer

Z=square root(R2+(XL-Xc)2)

Phase =tan inverse of((XL-Xc)/R)

Emax=120V

Imax=Emax/Z

C=25*(10^-6)F

L=340*(10^*-3)H

R=280 ohm

Xc=(1/wC)

XL = wL

solving from these we get

timax at =0.32sec
