Need help with how to calculate. How is current calculated?? Do you add up all the voltage drops and divide by the cap resistance? Is the amplitude RMS? Or should it be peak? Above solved ^ Replaced cap with a resistor with same Xc value. Made the calculations easier also made ac voltage 170 peak. Much eaiser.
