AIIMS 2010 Physics Transmission of electric power Assertion Reason Question
Assertion : It is advantageous to transmit electric power at high voltage. Reason : High voltage implies high current.
A: Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B: Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C: Assertion is true but Reason is false.
D: Both Assertion and Reason are false.
Correct Answer
Detailed Explanation
As P = VI, hence for the transmission of same power, high voltage implies less current. Therefore heat energy losses (H = I²Rt / I²R / 4.2) are minimized if power is transmitted at high voltage.
