Electricity is a phenomenon that takes place when electric charges are stable or moving. A fundamental particle, an electron, a proton, an ion, or some wider entity with excess positive and negative charges could be the cause of the electric charge. Like charges repel each other while positive and negative charges attract each other (e.g., protons attract electrons).
The physical effect caused by a moving electric charge is known as magnetism. A magnetic field may also cause excited particles to move, resulting in the generation of an electric current. The electric and magnetic components of an electromagnetic stream (like light) are also present. The wave’s two components move in an identical course but at a normal angle to each other.
Ohm’s rule is one of the most central and essential principles in electric circuits.
If both physical parameters and temperature stay unchanged, Ohm’s law notes that the voltage through a conductor is directly proportional to the current flowing through it.
V = IR,
where V is the voltage through the conductor, I is the current flowing through it, and R is the resistance to the current flow given by the conductor.
In this chapter, we learned about the basics of electricity and magnetism. We observed the magnetic effect of a current.
