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
Verified Correct Answer: D.
Physical Principles & Numerical Solution
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.
