Question:
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. 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.
Solution:
From Ohm's Law, V = IR R = V/I which is nothing but the slope of V-I curve, hence R = 5Ω
