Answer Posted / siddesh cs
under normal condition,transformer oil as low temperature compared to lv & hv winding because, oil is mainly used for cooling purpose as per the law of thermodynamics heat flows from hot end to coold end so heat transfer from winding to oil.

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?
