Question

AC power is transmitted from a power house at a high voltages as ________.

• A. power cannot be transmitted at low voltages
• B. the rate of transmission is faster at high voltages
• C. it is more economical due to less power loss
• D. a precaution against theft of transmission line

Answer 1

Answer: (C)

it is more economical due to less power loss

AC power is transmitted at high voltage so as to reduce the power loss in the wire during transmission which makes it even more economical. The high voltage is again get reduced to low voltage by using a step down transformer.
