1. ohm's law
The fundamental law expressing the relations between current, electro-motive force and resistance in an active electric circuit. It may be expressed thus:
(a) The current strength is equal to the electro-motive force divided by the resistance.
(b) The electro-motive force is equal to the current strength multiplied by the resistance.
(c) The resistance is equal to the electro-motive force divided by the current strength. All these are different forms of the same statement. Algebraically the law is usually expressed thus, (a) C = E. It may also be expressed thus: (b) E = C*R and (c) R= E/C, in which R denotes resistance, C denotes current strength, and E denotes electro-motive force.
