## Ohm's Law

What is Ohm's law?

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