Question

what are the demerits of A. C. current​

Answer 1

Explanation:

1)Peak value of A.C. is high and it is dangerous to use so better insulation is required.

2)It attracts person who touches it unlike D.C. which gives a repelling shock.

3)An A.C. is transmitted from surface of the conductor and hence need several strands of thin wires insulated from each other.

Answer 2

Answer One negative side of AC power is that many different standards have developed around the world. AC power can run at various frequencies, and some countries use other frequencies than others. The "standard" type to use is 230V/50Hz, which is more efficient but more dangerous than the 110 V used in the USA
