Dear Student,

given below is the difference between AC and DC signals,

AC Signals :

• AC is safe to transfer longer distance even between two cities, and maintain the electric power.
• The rotating magnets cause the change in direction of electric flow.
• The frequency of AC is depended upon the country. But, generally, the frequency is 50 Hz or 60 Hz.
• In AC the flow of current changes its direction backwards periodically.
• Electrons in AC keep changing its directions – backward and forward

DC Signals :

• DC cannot travel for a very long distance. It loses electric power.
• The steady magnetism makes DC flow in a single direction.
• DC has no frequency of zero frequency.
• It flows in a single direction steadily.
• Electrons only move in one direction – that is forward.
