Question

ASSERTION : alternating current is used in household supply REASON : ac electric power can be transmitted over long distance.

Answer 1

Answer:

both are correct but reason is not completely explain the assertion

Answer 2

Alternating current is used in household supply is correct and ac electric power can be transmitted over long distance is also correct but this reason is not completely explains the assertion because of following:

- Ac has higher voltage and lower current and this voltage can changed easily with transformer.

- At constant power transmission thin and light conductors are used in case of ac which leads to less loss in long transmission lines which is suffered by high voltage.

- Moreover , from household ac supply Dc current can be made easily as compared to other methods.
