Why is the electric shock from the DC supply is more dangerous than the shock from AC supply.
8 9729A 4-Pole D.C. Generator has a speed of 1500r.p.m. Then what will be the frequency of D.C. Generator ?
9 101321. 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?
