why do we need to use 3c+3e cable, normally i select only 3c+e cable and i think it is enough. pls explain the usefull of 3e cable ( in this project the earthing system is well done)

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?

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
