Plot a
graph between V and I and calculate the resistance of that
resistor.
Solution:
The voltage is plotted on x-axis
and current is plotted on y-axis. The values of the current for
different values of the voltage are shown in the given table.
The IV characteristic
of the given resistor is plotted in the following figure.
