Ohm's Law

Ohm's Law

Ohm’s Law states that at constant temperature the current through a conductor is directly proportional to the potential difference across its ends.
If V is the potential difference and I is the current, then
I Proportional V
V/I = Constant
The constant is the resistance R of the conductor.

Procedure:-

1- Make connections as shown in circuit diagram.
2- Take least count of ammeter and voltmeter.
3- Plug the key. Note the readings of voltmeter and ammeter.
4- Repeat the experiment by adjusting the rheostat.
5- Draw a graph between V and I.
