Difference Between Ac And Dc Current In Tamil. The direction of current flow will change at normal time interval then this kind of current is known AC or alternating current whereas the DC is unidirectional because it flows in a single direction only. Direct current DC doesnt change direction as AC does.
The power supplied by DC source is not convenient for long distance as it will diminish with the increment in the distance. While in the direct current it flows in a single direction steadily. The AC load can be capacitive inductive or resistive but the load on DC is always resistive.
AC drives also known as VFD convert the AC supply to DC using converter rectifier and invert it back from the DC to the AC using inverter to run the AC motors.
The major difference between AC and DC is that DC is unidirectional current while AC is bidirectional Current. AC drives also known as VFD convert the AC supply to DC using converter rectifier and invert it back from the DC to the AC using inverter to run the AC motors. In Direct Current the flow of electrons is in a constant direction without changing at intervals and is accomplished by placing steady magnets on the wire. The AC load can be capacitive inductive or resistive but the load on DC is always resistive.
