What is the statement of Ohm’s law?

Hint: Ohm's law is one of the essential laws in physics. It gives us the relationship between current and voltage through the circuit. Ohm's law introduced us to the concept of resistance. We can start to answer this question by defining current, voltage and the resistance of a circuit.

Complete step by step answer:
Let us start by defining what voltage, current and resistance is.
Voltage: This is also known as potential difference is the difference between the potentials at two points.
Current: Electrical current is defined as the flow of charged particles like electrons through space.
Resistance: It is the opposition offered by a material for current to flow through it.

Ohm's law states that “the voltage or potential difference (V) between two points is directly proportional to the current or electricity (I) flowing through the circuit”.
$V \propto I$
$\Rightarrow V=I \times R$
Here, $R$ is the resistance which is a constant.
The above formula is used to find the voltage, current or resistance.

Note: We use ohm's law to find the current rating of specific electronic devices like laptops. Another application is detecting the value of the current rating of a normal circuit. Some applications of ohm's law can be observed in Kirchhoff's laws where individual loops are considered and the value of current and voltage is found using the ohm's law.
