Shouldn't that be "Soh?"
Oops, you are right.

When I was preparing for my journeymans and masters exams I would practice generating the Ohm's law and Power wheels by starting with the base formulas E=IxR and P=IxE. Then by using algebraic manipulation you can come up with the rest of the equations.
For example using E=IxR we manipulate the equation so that we get R by itself by dividing both sides by I and you will get R=E/I.

What section of textbook algebra deals with using two separate equations variables to come up with the rest of the equations?
When you start with 2 equations that both contain one or two common values you can combine the 2 equations.
For example we start with E=IxR and P=IxE so the common value is I & E. Now if I want to find P when I know resistant and amperage then we must combine the 2 formulas. so by using algebraic manipulation we know that I=E/R so we can replace the I in P=IxE with P=(ExE)/R.

Can you show those examples using formula with square root of PXR and P/R?

I just use the two separate laws/equations. I can do it without a calculator, and I'm not in such a hurry that I have to save a step or two.He is looking to find the formulas when the wheel isn't present...
