FOR DC CIRCUITS ENTIRE VOLTAGE COME across THE capacitor SO CURRENT IS ZERO...
IN LCR CIRCUITS CURRENT VARIES ACCORDING TO FREQUENCY ( FOR AC CIRCUITS)
AT A PARTICULAR FREQ (F0) CALLED RESONANCE FREQ THE CURRENT IN THE RLC CIRCUIT IS MAXIMUM.
  1. CURRENT IS INVERSLY proportional TO impedance of LCR NETWORK
