Power supply is transmitted at a very high voltage and low current in order to?

A. make pass through the transformers
B. increase the power supply
C. make it travel fast
D. prevent overheating of the coil

Correct Answer:

Option D – prevent overheating of the coil

Explanation

Heat generated in a wire carrying current, H = 1²Rt. So, when the voltage is high and the current is low heat generated in the wire will be minimal.
Therefore, high voltage and low current prevent overheating of the coil.
