Question

what are direct and alternating current (AC) why is alternating current preferred over direct current (DC)​

Answer 1

Answer:

Following are the advantages of alternating current over direct current: AC is less expensive and easy to generate than DC. The distance covered by AC is more than that of the DC. The power loss during transmission in AC is less when compared to the DC.

Explanation:

Answer 2

Direct current is the current in which charge flows in unidirection

Alternating current is the current charge flows backward and forward direction periodically.

AC can be transmitted with much lower energy as compared to DC

In DC there is more loss of energy

alternating current can be generated easily
