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.
AC-The frequency of the alternating current is 50Hz or 60Hz depending upon the country.
DC-The frequency of the direct current is zero.
AC-It reverses its direction while flowing in a circuit.
DC-It flows in one direction in the circuit.
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
9- Power Factor
AC-Lies between 0 & 1.
DC-it is always 1.
AC-Sinusoidal, Trapezoidal, Triangular, Square.
DC-Pure and pulsating.
AC– power Generation Equipment have more efficiency
DC– power Generation Equipment have less efficiency
