Question

17. State Ohm's law. Draw a circuit diagram for
the verification of Ohm's law.​

Answer 1

Explanation:

When current is directly proportional to Potential difference and let R as constant at constant temperature so value of potential diff is the product of current and resistance.

V = IR

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.
