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 (Ampere) 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.

Solution :-

The plot between voltage and current is known as IV characteristic. The current is plotted in the y-axis, while the voltage is plotted in the x-axis. The different values of current for different values of voltage are given in the table. The I and V characteristics for the given resistor is shown below.

The slope of the line gives the value of resistance.

The slope can be calculated as follows:

Slope = 1/R = BC/AC = 2/6.8

To calculate R,

R = 6.8/2 = 3.4 Ω

The resistance of the resistor is 3.4 Ω
