Definitions :-
AC :-
The current that changes its magnitude and polarity at regular intervals of time is called an alternating current.
The sine wave of Alternating Current is shown bellow -
DC :-
Direct current is the unidirectional flow of an electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
Discussion :-
The current which comes from the power house to our home is AC. But most of the electronic product does not work in AC. So, there are some electronic instruments were planted to convert the AC to DC.
In late 1880s, Thomas Alva Edison invented 'Direct Current' or 'DC'.
And few times later, Nikola Tesla invented 'AC' or 'Alternating Current'.
Although, most of the electronic product works in Direct Current, but it is quite difficult to distribute Direct Current from the power house to our home because in this case a huge amount of heat will be produced according to 'Jule Effect' and most of the electricity will be destroyed. For this reason, Nikola Tesla invented Alternating Current.
