State Ohm's law and draw a neat labelled circuit diagram containing a battery, a key, a voltmeter, an ammeter, a rheostat and an unknown resistance to verify it?

Ohm' Law:

If a voltage source is applied to a circuit, and current is varied using the rheostat in the circuit, then the relationship between the voltage across the load and the current through it can be obtained through the Ohm's Law.

Ohm’s law states that the voltage potential difference between two points is directly proportional to the current and inversely proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR. This relationship between current, v...
