Can you explain me What is difference between ac and dc?


Ac and DC both are types of electric current flow where AC stands for Alternating Current and DC stands for Direct Current.

The major difference between Alternate Current and Direct Current lies in the direction in which the electrons flow.

In AC,  electric current flow switches its directions periodically. While in DC the current flows in a single direction in a steady voltage.

Also, the frequency of AC signals are very large, while that of DC are almost zero.
