Electrical Machines 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% kepping the circuit conditions unaltered, then the Voltage to which the machine would build up will increase to a value greater than 1.25 times 220 V increase to 1.25 times 220 V increase to value lying between 220 V and 1.25 times 220 V not change and remain at 220 V increase to a value greater than 1.25 times 220 V increase to 1.25 times 220 V increase to value lying between 220 V and 1.25 times 220 V not change and remain at 220 V ANSWER DOWNLOAD EXAMIANS APP
