what is cascade speed control device?and how this device control the speed of motors?
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

i want to run 11kv star connected motor in 6.6kv with delta connected throught inverter, is it possible?
it is in our knowledge tht right plug of supply of residential suppy system is phase n other is neutral...howevr the battery charger of mobile works in both ways...i mean it is not restricted in only one direction.ny of the holder of charger can hav phase .so y is it not lik tht phase of supply must b connected 2 phase of charger...?
