In the field of electrical and electronic engineering knowing about alternating current is very much important.
What is Electrical current?
The movement of a free electron in a conductive material is called an electrical current.
What is an alternating current?
If the movement of electrons periodically changes their direction and magnitude, then it is called alternating current (ac current).
How do understand alternating current in a simple way?
In the alternating current movement of Electrons in a conductor will be front and back. The graphical representation of alternating current will form a sinusoidal waveform,
For instance, Consider a bird as an AC electric power. Birds use their wings to fly in a free environment. So consider wings as electrons. Now, wings move up and down but the movement of the bird will be in a straight line
What is the use of alternating current?
Electrons have the power to operate electrical loads such as ceiling fans, earphones, television, etc.
