PHYSICS F5 I ELECTROMAGNETISM I GENERATION AND TRANSMISSION OF ELECTRICITY I PART 2

Knowledge you should achieved after following this lesson..

1. When a current, I, flows in a cable, the power loss, P through heating is given by P=I2R where R is the resistance in the cable. Heat losses can be minimized by decreasing the current, I in the transmission cables.

2. To transmit a given power, P=VI, the current, I can be decreased only by compensating with an increase in voltage, V.

3. High-voltage power lines are used to transmit power over long distances.
