A) Since resistance of conductor decreases with increase of voltage
B) Since current decreases with increase of voltage
C) Both of the above
D) None of the above
Correct Answer: B
Solution :
Option [b] is correct. Explanation: At generating station, normally voltage is stepped up to around thousands of volts. Power losses increase with the square of current. Therefore, keeping voltage high, current becomes low and the loss is minimized.
