Power supply is transmitted at a very high voltage and low current in order to?
- make pass through the trasformers
- increase the power supply
- make it travel fast
-
prevent overheating of the coil
The correct answer is: D
Explanation
H eat generated in a wire carrying current, H = 12 Rt.
so, when voltage is high and current is low heat generated in the wire will be minimal.
Therefore, high voltage and low current prevent overheating of the coil.
