in small capacitor we use uf( micro farad) and in big quantity we used kvar. i want to know that in 1 kva how much will b uf(micru farad).
2 5208What will hapen if we connect more capacitors than required for powerfactor control? Exactly what will be the effect on power system?
2 5150Can 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
3 4663if we connect a ohmmeter across shorted capacitor .what will be the reading..will it be zero or infinity

In PFI plant one stage capacitor connection is directly connected(with out megnetic contact controll). but why?
what is the series parallel connection of capacitors? and how can we use these application in three phase motors for controlling torque?
How shall i select the value of capacitor or inductor in a system?
Power factor =1.000 at factory in supply. However, PF = 0.8 at motor end. Current = 100 Amp, Voltage = 400 V. What is the power distribution loss? Can I reduce it by adding capacitor at the load feeder?
how a resistor resists to flow the current?how an inductor oppses the sudden change in current?how a capacitor opposes a DC voltage.
how we start 40w tube light with 4 diodes,2capacitors,1 choke and without starter.(a product avilable in market which lights burnt tube lights also)
i am going to correct power factor of 1600kw induction motor,when i calculate capacitance of capacitor it is three time more in star connection than delta. if motor is star connected which connection i shall adopt for capacitors and reason for adopt this connection
