Question

experimental setup of Ohm's law and write an activity to demonstrate and Verify Ohm's law​

Answer 1

Statement of Ohm's Law: Ohm's law states that at a constant temperature, current 'I' through a conductor between two points is directly proportional to the potential difference or voltage 'V', across the two points. That is, ... This constant is called as the resistance (R) of the conductor.

Answer 2

Potential difference across the two points of a metallic conductor is directly proportional to current passing through the circuit provided that temperature remains constant.

• Mathematical expression for Ohm’s law

V ∝ I

⇒ V = IR

→ R is a constant called resistance for a given metal.
