Question

Plot a graph between V and I and calculate the resistance of the resistor.

Answer 1

hope this helps.
the answer is in the attachment.

Answer 2

In this graph, RESISTANCE, R = 1 ohm.

◆ RESISTANCE ,R = V / I

Where, V- VOLTAGE , I - CURRENT.

◆ So, finding resistance from V I would be , it's slope.

◆Refer the attachment below,

◆Considering this graph,

◆ Resistance R , it's slope is ∆V / ∆I

Slope = (2 - 1) / (2 - 1)

= 1 V / 1 A = 1 ohm.

◆Thus, Resistance is 1 ohm.
