A DC shunt generator builds up to a voltage of 220 V at no load while running at its rated speed.
If the speed of the generator is raised by 25% keeping the circuit conditions unaltered, then the Voltage to which the machine would build up will
A. not change and remain at 220 V
B. increase to 1.25 times 220 V
C. increase to value lying between 220 V and 1.25 times 220 V
D. increase to a value greater than 1.25 times 220 V
