An industrial step-down transformer is used to supply power from an electric utility line to an electric vehicle (EV) fleet charging station.

The parameters of the transformer are shown in the table below:

ParameterValue
Potential difference across primary coil11 000 V11\,000\text{ V}11000 V
Current in secondary coil625 A625\text{ A}625 A
Potential difference across secondary coil440 V440\text{ V}440 V

Assuming the transformer is 100%100\%100% efficient, calculate the current drawn by the primary coil of the transformer.
