From the generating station to each substation power is transmitted at a very high voltage so as to reduce
A
hysteresis loss
B
eddy current loss
C
magnetic flux leakage
D
heating in the coils
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Power is transmitted at very high voltages primarily to reduce heating in the coils(cables).
High Voltage: Lowers current, minimizing resistive (I\(^2\)R) losses, which cause heating.
Eddy Currents: While they can be a concern in certain applications, such as transformers, they are not the primary issue in high-voltage transmission.
