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.
