Question

hey guys mughe thoda long m chahiye answer can u give

Answer 1

HEY DEAR , HERE IS YOUR ANSWER. ✌✌

bcuz ( i ) it is easy FOR US to maintain and change the voltage of AC electricity for transmission and distribution.

( ii ) when a large fault occurs in a network , it is easier to interrupt in an AC system , as the sine wave current will Naturally tend to 0 at some pointmaking the current easier to interrupt.

( iii ) AC transmission cost is much lower than the equivalent DC transmission.

( iv ) from power stations, AC is produced SO IT IS BETTER TO USE AC THEN DC instead of converting it.

Answer 2

In ac systems average power or let's say heat generated over transmission of current is less as compared to DC transmission which reduces the risk of overheating in transmission lines thus reducing the cost of repairment which in turn makes transmission cheaper.

Hope it helps.
