why the current leads voltage in the case of a capasitor
Answer Posted / prasad
It must be first understood here that the capacitor
current leads the voltage across capacitor & not the supply
voltage.
Whenever A.C. voltage is applied across the capacitor,
initially free electrons start conducting current offering
zero resistance & thus no voltage across the capacitor. As
the capacitor plates start getting charged (Polarity opp to
supply) it starts offering resistance to current & voltage
starts to appear across capacitor.
