Find the resistance of the wire using the graph​

Answer»

EXPLANATION.

Resistance of the WIRE using graph.

As we know that,

By OHM's law.

⇒ V = IR.

⇒ R = V/I.

Potential difference (V) = 2.

Current (I) = 0.1 ampere.

Put the values in the equation, we get.

⇒ R = 2/0.1.

⇒ R = 20 Ω.

Potential difference (V) = 4.

Current (I) = 0.2 ampere.

Put the values in the equation, we get.

⇒ R = 4/0.2.

⇒ R = 20 Ω.
