## Ohm's Law equation, explanation

Ohm's law is one of the basic laws on which electrical and electronics engineering in general are built. This law explains the relationship between voltage, current and electrical resistance , In this article, we will show you some mathematical equations associated with this law.

### Definition of Ohm's Law:

Ohm's Law equation |

This law helps to explain how these three key parameters are interconnected and influence each other within a circuit.

#### Ohm's law units:

The unit of electrical potential or tension is: volt, and it is measured with a voltmeter.

The unit of electrical resistance is: ohm, and it is measured with an ohmmeter.

The unit of electrical current is the ampere, which is measured with an ampere-meter.

#### How to understand Ohm's law:

Ohm's law relationship is a very simple relationship and it is easy for anyone to remember it, but it may be somewhat complicated for some, and this figure below shows the triangle of Ohm's law. All you have to cover is any amount you want to calculate, and the relationship between other physical quantities will appear :
