Why is it advantageous to transmit electric power long distances at high voltages?
To explain: The advantages of transmitting electric power through long distances at high voltages.
Explanation of Solution
Introduction:
Power loss in transmitting wires is inversely proportional to voltage.
Let power P be delivered via transmission lines or cable having resistance R.
Let V be the voltage and I be the current at which power is delivered.
Hence,
Power dissipated in transmission cables is denoted by
Conclusion:
Power loss through transmission cables
