The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below –

I (amperes) 0.5 1.0 2.0 3.0 4.0

V (volts) 1.6 3.4 6.7 10.2 13.2

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

NCERT Question 7 The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below – Plot a graph between V and I and calculate the resistance of that resistor. By Ohm’s law V = I R ∴ R = 𝑉/𝐼 To find resistance, We find the mean of resistance in the 5 cases ∴ R = (3.2 + 3.4 + 3.35 + 3.4 + 3.3)/5 R = 16.65/5 R = 3.33 Ω
