Answer / muniraja

transformer is nothing but power producing equipment.So the
powre p=V*I.v=Voltage,I=Amps.the minimum rating of the
distribution transformer is 1000V.i.e 1 Kilo
volt,v=volts,&I=amps.So thats while we can saying in KVA.

Moter rating in H.P & 1 H.P=0.732kiloWatts.
So moters having load is almost Drives.

how does relay works?

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
