Question

State the disadvantage of direct current.

Answer 1

direct current is costly

it has low efficiency

it is costly to produced

Answer 2

DC current

Explanation:

Disadvantages of DC (Direct Current) current are:

1. Difficulty of generating the DC at high voltage because of the commutation problems.
2. The voltage in DC system cannot be easily stepped up for high-voltage transmission. Whereas in AC system, it can be easily done with a transformer.
3. DC circuit breakers and switches offer more limitations.
4. So DC correct is more difficult to transmit and hence expensive, hence not practical.
