In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
AC is more dangerous than DC current
AC is more dangerous than DC current

Can u write some more points pls.... the ans. Is for 5 marks..
also AC can be transmitted over long distances without much loss of energy unlike DC
frequency of AC in India is 50 hz whereas frequency of DC Is 0 hz
AC can be easily converted into DC
Thnx for ur help

hey dear here is ur answer
AC Vs DC
*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.
*Cause of the direction of flow of electrons
AC-Rotating magnet along the wire.
DC-Steady magnetism along the wire.
*Frequency :
AC-The frequency of alternating current is 50Hz or 60Hz depending upon the country.
DC-The frequency of direct current is zero.
*Direction :
AC-It reverses its direction while flowing in a circuit.
DC-It flows in one direction in the circuit.
*Current :
AC-It is the current of magnitude varying with time
DC-It is the current of constant magnitude.
*Flow of Electrons :
AC-Electrons keep switching directions - forward and backward.
DC-Electrons move steadily in one direction or 'forward'.
*Obtained from :
AC-A.C Generator and mains.
DC-Cell or Battery.
*Passive Parameters :
AC-Impedance.
DC-Resistance only
*Power Factor :
AC-Lies between 0 & 1.
DC-it is always 1.
*Types :
AC-Sinusoidal, Trapezoidal, Triangular, Square.
DC-Pure and pulsating.
hope it helps u dear
