Ohm's law for electrical circuits can be read off a triangular diagram formed from the variables , and :

V

I

R

The diagram represents Ohm's law, solved for each of the variables, namely:

I=

V

R

V=IR

R=

V

I

Several other formulas in physics and chemistry, in which it is useful to solve for each of its variables, can likewise be represented by analogous diagrams. You can select diagrams pertaining to electrical power, ideal gases, density, speed and distance. A diagram for the Pythagorean theorem is also shown, in which the relationships involve addition and subtraction, rather than multiplication and division.

This Demonstration also shows a diagrammatic representation for the thermodynamic potentials and Maxwell's relations.

Run the tooltip over a symbol in a diagram to show the formula solved for that variable.
