Ohm's Triangle

I have had an epiphany! This triangle is a remarkable tool to memorize Ohm's Law. The trick to the triangle is that whichever variable you are trying to solve for, you cover it up and use the resulting variables as they appear in the triangle.
For example: If you want to find V, you multiply I(R)
If you want to find I, divide V/R
If you want to find R, divined V/I
Very glad I found this!
