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 (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.
R = (V2-V1)/(I2-I1)
R = (6.7-3.4)/(2.0-1.0)
R= 3.3V/1.0A
R= 3.3 Ω
