Answer Posted / bele vijay kumar
For single phase circuits Neutral busbar size is equal to phase busbar & in 3 ph
systems it is either equal to phase busbars or lesser. It is determined on factor
such as Earthing of the Electrical system and the 3rd harmonics.

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
