We have noticed many times about AC and DC but very few of us know exactly the difference between them,
and this is mostly the favorite question of interviewer, so today we will see their main difference between AC and D

1- Amount of energy that can be carried
AC-Safe to transfer over longer city distances and can provide more power.
DC-Voltage of DC cannot travel very far until it begins to lose energy.
2- Cause of the direction of flow of electrons
AC-Rotating magnet along the wire.
DC-Steady magnetism along the wire.
3- Frequency
AC-The frequency of alternating current is 50Hz or 60Hz depending upon the country.
DC-The frequency of direct current is zero.
4- Direction
AC-It reverses its direction while flowing in a circuit.
DC-It flows in one direction in the circuit.
5- Current
AC-It is the current of magnitude varying with time
DC-It is the current of constant magnitude.
6- Flow of Electrons
AC-Electrons keep switching directions – forward and backward.
DC-Electrons move steadily in one direction or ‘forward’.
7- Obtained from
AC-A.C Generator and mains.
DC-Cell or Battery.
8- Passive Parameters
AC-Impedance.
DC-Resistance only
9- Power Factor
AC-Lies between 0 & 1.
DC-it is always 1.
10- Types
AC-Sinusoidal, Trapezoidal, Triangular, Square.
DC-Pure and pulsating.
11- Equipments
AC– power Generation Equipments have more efficiency
DC– power Generation Equipments have less efficiency
