Question

Find the resistance of the wire using the graph​

Answer 1

Step-by-step explanation:

YOU CAN TAKE ANY OF THE POINT ON GRAPH.

I AM TAKING BOTH THE POINTS TO SHOW YOU THAT THE ANSWER WON'T DIFFER.

We know that,

V = IR

Taking V = 2 and I =0.1

2 = (0.1)R

R = 20 ohm

Taking V = 4 and I =0.2

V =IR

4 = (0.2)R

R = 20 ohm

Answer 2

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.
