Question

What is the actual difference between ac & dc ?

Answer 1

There can be many diferences between DC and AC current.

1) we can store only DC current in the batteries.

2) AC current have higher magnitude than the DC current.

Answer 2

Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction.
