Question

what is difference between direct current (DC) and alternating current (AC)?​

Answer 1

Answer:

DIFFERENCE

Explanation:

AC

1) The current which changes it's direction or reverses periodically is called alternating current.

2) Loss of energy in form of heat is less

3) In India,

Frequency of AC is 50Hz

4) Value of voltage can be changed by using transformers.

DC

1) The current which doesn't changes its direction is called Direct Current.

2) Loss of energy is high

3) Frequency is 0Hz

4) Voltage cannot be altered
