**Hint**

It is a mathematical expression commonly used to solve circuit analysis problems.

If all physical conditions and temperature remain constant, Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through.

In an electrical circuit, Ohm's Law can be expressed as a formula to describe and calculate the relationship between voltage (V), current (I), and resistance (R).

$$$V=IR$$$

It can also be expressed as,

$$$I=\frac{V}{R}\;or\;R=\frac{V}{I}$$$

If all physical conditions and temperature remain constant, Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through.
