1. The problem statement, all variables and given/known data Find the magnitude and phase of the current flowing through the galvanometer whose internal resistance is negligible.C1=C, C2=0, Cx=2C, R2=R3=R, Rx=0 http://www.freeimagehosting.net/uploads/4ce4800510.png 3. The attempt at a solution Magnitude of the current: Using the Thevenin equivalent circuit, Z1 = 1/jwC1 = 1/jwC Z2 = R2 || 1/jwC2 = R Zx = Rx + 1/jwCx = 1/jw2C Z3 = R3 = R Rth = (Z1 || Z2) + (Zx || Z3) Vth = V from c to b = Vc - Vb = Vac - Vab = E (Z1/(Z1+Z2) - Zx/(Zx+Z3)) Ig = Vth/Rth Would this be correct? Have no idea on how to get the phase of the current.... Thanks!
