Short-circuit test is performed on a transformer with a certain impressed voltage at rated frequency. If the short-circuit test is now performed with the same magnitude of impressed voltage but at a frequency higher than the rated frequency, then
  • a)
    the magnitude of current and power factor both will increase
  • b)
    the magnitude of current will decrease but the power factor will increase
  • c)
    the magnitude of current will increase but the power factor will decrease
  • d)
    the magnitude of current as well as the power factor will decrease
Correct answer is option 'D'. Can you explain this answer?
