Can a 50Hz transformer be used for 25 Hz, if the input voltage is maintained constant at the rated value corresponding to 50 Hz? | |
A. | Yes, since the voltage is constant current tevel will not change. [Wrong Answer] |
B. | No, flux will be doubled which will drive the core to excessive saturation [Correct Answer] |
C. | No. owing to decreased resistance of transformer, input current will he doubled at the load, [Wrong Answer] |
D. | Yes, at constant voltage, insulation will not be overstressed [Wrong Answer] |
