A step-down transformer at a steel manufacturing plant is used to operate an industrial electric arc furnace. The primary coil of the transformer is connected to a 33 kV33\text{ kV}33 kV distribution line.
The potential difference across the secondary coil is 110 V.
The primary coil has 6000 turns.
Calculate the number of turns on the secondary coil.
