If a fixed amount of power is to be transmitted over a certain length with the fixed power loss then_____,

The weight of the conductor required will be inversely proportional to the square of the voltage and that of the power factor of the load

The weight of the conductor required will be proportional to the voltage

The weight of the conductor required will be inversely proportional to the voltage and that of the power factor of the load

The weight of the conductor will be proportional to the square of the voltage and directly proportional to the power factor of the load.
