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

Question

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.

Answer 1

The plot between voltage and current is called VI characteristic. The voltage is plotted on x-axis and current is plotted on y-axis.
