An industrial electric arc furnace is connected to a high-voltage distribution line via a step-down transformer.
The transformer has 1200 turns on its primary coil and 18 turns on its secondary coil.
An alternating potential difference of 11 kV11\text{ kV}11 kV is applied across the primary coil.
Calculate the potential difference across the secondary coil. Give your answer in volts.
