The fundamental principle of electricity.

The Ohm’s Law is the fundamental law of electricity and it helps us understand the relationship between current, voltage and resistance. Ohm’s Law explains that the amount of electrical current flowing through a metal conductor of a circuit is directly proportional to the voltage across it, for any given temperature. Ohm derived this relationship in a simple mathematical form as follows: current (I), voltage (V) and resistance (R):

This law can be verified by means of the circuit above. The student can calculate the value of the resistance by applying a voltage value and measuring the corresponding current value and their results can be graphed.

The student can also vary the value of the resistance and verify investigate the consistency of Ohm’s Law.
