Answer / raki

in leading pf curren will have more harmonics

Answer / abhi

the genrator is design for lagging p.f. because normally
genrator run on normal p.f.,but sometimesthe force of input
is very high.so in this way the generator does not
working.so we design generator for lag p.f.

Answer / shekhar saxena

IF generator is designed for leading power factor then, the
leading current will harms the windings of generator and
ultimately the there will be damage of whole machine.

show that power dissipated by a pure inductor exited by a sinusoidal voltage source v = vm sin wt is zero

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
