State one main difference between AC and DC
Dear student
Find the differences below.
Alternating Current Direct Current
Amount of energy that can be carried:
Safe to transfer over longer city distances and can provide more power.
Voltage of DC cannot travel very far until it begins to lose energy.
Flow of Electrons:
Electrons keep switching directions - forward and backward.
Electrons move steadily in one direction or 'forward'.
Cause of the direction of flow of electrons:
Rotating magnet along the wire.
Steady magnetism along the wire.
Frequency:
The frequency of alternating current is 50Hz or 60Hz depending upon the country.
The frequency of direct current is zero.
Direction:
It reverses its direction while flowing in a circuit.
It flows in one direction in the circuit.
Current:
It is the current of magnitude varying with time
It is the current of constant magnitude.
Types:
Sinusoidal, Trapezoidal, Triangular, Square.
Pure and pulsating.
Obtained from:
A.C Generator and mains.
Cell or Battery.
Regards
