If it should happen that a high voltage electric line should drop from the pole and make contact with a car, the person in the car should jump out of the car with both feet at the same time, rather than stepping out, one foot at a time. Explain the rationale behind this safety tip.

3. Electric power is transferred at very high voltages over long distances. Transmission of high voltage Explain how it reduces power loss on the lines. 4. If two points have the same potential, this test load will be taken from one point to another. Does it mean that no work will be carried out during the course? This need no force application shows that it is not? Discuss.
