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 Ohm�s law
1.
Unknown current
2.
Unknown voltage
3.
 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)
