Generator loading & No load running has no effect its
paramaters, means generator run at no load as required.
Second part of question, generator are normally designed to
1.2 to 1.5 times of nominal speed to run for one minute
without any problem. Very generation system has a speed
controller & voltage controller which responce to these
condition within 1 to 2 seconds. I suggest interviwer shall
not confuse to candidate at interview.

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
