Yes, E=I x R, but not correct to say "or" E/(I x R); to use the transformation correctly would be to say E/(I x R)=1 (by dividing both sides by (I x R)).

Correct..

Remember the old Ohms Circle tool for conversions ????

The circle area is divided into a top half and 2 bottom quarters.
The top is E , the bottom/left is I and the bottom/right is R.
By covering the unknown value you are looking for , you then know to divide, or multipy the others to get your answer..

I=E/R
E=IxR
R=E/I

Hey Alex , let's try Ohms for $600.... ding--ding...
