Question

1.What will happen to the output current of a D.C. generator if we:-
(a) increase the number of turns in armature coil?​

Answer 1

Answer:

When DC Generator fails to build up the voltage, what are the reasons? No residual magnetism, reversal of field connections and the resistance in the load circuit may be greater than critical resistance.

Explanation:

As there is small voltage is there across the terminals of DC Shunt Generator and Switch S is closed, therefore a small current will start flowing through the field circuit of DC Shunt Generator which in turn will produce magnetic flux and if the produced magnetic flux adds the residual magnetic flux then net flux will
