Question
At what voltage is the electric power from the generating station transmitted? Give reason to your answer.
✓
Answer
Electric power from the generating station is transmitted at $11 kV$ because voltage higher
than this causes insulation difficulties, while the voltage lower than this involves high
current and loss of energy in form of heat $\left(I^2 R t\right)$.
