Ohmís law

Ohm's law is the main basic electrical law and defines the resistance of a device to the flow of electrons.

There are three different notations of Ohmís law

1. Ohm's law Unknown current Unknown current

2. Ohm's law Unknown voltage Unknown voltage

3. Ohm's law Unknown 
resistance Unknown resistance

(Most people can remember a picture easier than a mathematical formula. By knowing any two values you can figure out the third. Simply put your finger over the portion of the symbol you are trying to figure out and you have your formula)

1. Ohm's law Unknown 
current

2.Ohm's law Unknown 
voltage

3. Ohm's law Unknown 
resistance
