Electrical power is transmitted at a high volta... - JAMB Physics 2018 Question
Electrical power is transmitted at a high voltage rather than a low voltage because the amount of energy loss is due to
A
Heat dissipation
B
Production of eddy currents
C
Excessive current discharge
D
Excessive voltage discharge
correct option: a
The primary reason that power is transmitted at high voltages is to increase efficiency. As electricity is transmitted over long distances, there are inherent energy losses along the way. High voltage transmission minimizes the amount of power lost as electricity flows from one location to the next. ~ Betaengineering.com
