A short-circuit experiment is conducted on the high-voltage side of a 200 kVA, 5000 V/250 V, single-phase transformer in its nominal frequency. The short-circuit voltage is found as 4300 V and the short-circuit current and power are 40 A and 170000 W, respectively. Find the series impedance of the transformer referred to its low voltage side.

the answer is 3.1 his answer is wrong mines is right

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
