Power supply is transmitted at a very high voltage and low current in order to
-
A.
make pass through the trasformers -
B.
increase the power supply -
C.
make it travel fast -
D.
prevent overheating of the coil
Correct Answer: Option 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.
