AC vs DC (THE COMPLETE DIFFERENCE BETWEEN AC & DC)

COMPARISON BETWEEN AC & DC

1.Difference between AC & DC in tabular form

AC (Alternating Current)	DC (Direct Current)
1. AC is developed by NIKOLA TESLA	1. DC is developed by THOMAS EDISON
2.Ac is safe to transfer over longer city distance & provides more power (EFFICIENT)	2. DC is for short distances. It losses more energy during travelling far distance . Provides less power (INEFFICIENT)
3. Rotating magnetism along the wire.	3. Steady magnetism along the wire.
4. FREQUENCY of AC is 50-60 Hz depending on places (countries)	4. FREQUENCY of DC is 0Hz
5.It reverses its direction periodically while flowing in a circuit.	5. It is unidirectional in a circuit.
6. It is the current of magnitude varies with time	6. Current of magnitude is constant.
7.Electrons keep switching direction (BOTH FORWARD & BACKWARD)	7. Electrons only move forward.
8.SOURCE of AC is Generator	8. Source of DC is cell or battery
9. It is Impedance	9. It is Resistance
10.Lies between 0 & 1	10. It is always 1
11. AC is more complex than DC	11. DC is simpler than AC
12. There is nothing constant in DC	12. Everything constant in DC.
13. When graphed AC look like WAVE or sinusoidal structure.	13. When graphed DC look like two flat line. (PARALLEL LINES)
14. AC is known as long distance current.	14. DC is known as short distance current.
15. Transformer work in AC	15. The transformer has no value in DC.
16. AC is not safer compared to DC	16. DC is safer compared to AC
