Question

The values of potential difference V applied across a resistor and the
corresponding values of current I flowing in the resistor are given below:
V(volts) 2.5 5.0 10.0 15.0 20.0
I(amperes) 0.1 0.2 0.4 0.6 0.8
Plot a graph between V and I and calculate the resistance of the resistor.

Answer 1

Answer:

The values of current (I) flowing through a given resistor of resistance (R), for the corresponding values of potential difference (V) across the resistor are as given below

V(volts) 0.5 1.0 1.5 2.0 2.5 3.0 4.0 5.0

I (amperes) 0.1 0.2 0.3 0.4 0.5 0.6 0.8 1.0

Plot a graph between current (I) and potential difference (V) and determine the resistance (R) of the resistor.
