Question

what is the difference between AC CURRENT AND DC CURRENT

Answer 1

HEY ✌️
➡️DIFFERENCE BETWEEN AC AND DC CURRENT:--

➡️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.

Answer 2

DC current


1. electric charge flow in one direction

2. the frequencies of DC current is zero

3. the source of availability is battery or cell

4 .DC current have only resistance


AC current


1.electric charge changes its direction periodic

2. the generating frequencies is 50hz to 60 hz in a current

3 .the source of availability is generator

4. ac current have resistance with capacitor or inductor
