## Ohm’s Law – The principle of Electronic Circuits

There are many properties of electricity but some of the most basic are explained by Ohm’s Law. Ohm’s Law describes the relationship between current, resistance, and voltage. Below are simple definitions of each, and following the definitions is a good analogy to help in understanding how these properties relate. Current = the flow of electric charge, the movement of electrons […]
