Ohm S Law Power Formula Wheel

The wheel below is a handy tool and memory jogger.

Ohm s law power formula wheel. Just enter 2 known values and the calculator will solve for the others. It looks more complicated but in reality it s easy to use you may need a calculator and it works the same way as the previous charts. Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The ohm s law wheel represents all possible relationships between power p resistance r current i and voltage v.

R is the resistance measured in ohms ω. This is essentially what the calculator does and is just a representation of the algebraic manipulation of the equations above. Now we re getting somewhere. Ohm s law formula wheel.

Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. P is power measured in watts. Simple to use ohm s law calculator. The combination of ohm s law and joule s law gives us 12 formulas where 2 of the 4 variables are known.
