Question

Difference between Ac current and Dc current​

Answer 1

Explanation:

• AC is safe to transfer longer distance even between two cities, and maintain the electric power.

while DC cannot travel for a very long distance. It loses electric power.

• The rotating magnets cause the change in direction of electric flow.

while The steady magnetism makes DC flow in a single direction.

• The frequency of AC is depended upon the country. But, generally, the frequency is 50 Hz or 60 Hz.

while DC has no frequency of zero frequency.

• In AC the flow of current changes its direction backwards periodically.

DC flows in a single direction steadily.

• Electrons in AC keep changing its directions – backward and forward

While Electrons only move in one direction – that is forward.

Answer 2

Explanation:

Electric current flows in two ways as an alternating current (AC) or direct current (DC). The main difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, while electrons keep switching directions, going forward and then backwards in AC.
