pHASE IS THE VECTORIAL REPRESENTATION OF VOLTAGE WITH
RESPECT TO CURRENT.

Answer / mrityunjay pandey

phase in electrical engg means the angle which is made by one vector (say-current) with respect to a base vector (say-voltage)..as we know in inductor current lags voltage ,so we take voltage as reference and measure the angle made by current phasor,suppose we got 30 degree angle .then the power factor i.e. cos (PHI)=cos(30 degree)=0.866..similarly current leads voltage in capacitor..

Answer / rana

Phase is the term which define the position of a rotating vector on vertical axis at any instant.Normally it used to define the angular value of alternator generation like current and voltage at that instant.

Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
