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(amepere)
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.
Question 3 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:
Plot a graph between current (I) and potential difference (V) and determine the resistance (R) of the resistor. By Ohm’s law
V = I R
∴ R = 𝑉/𝐼 V (Volts)
I (Amperes)
To find resistance,
We find the mean of resistance in the 10 cases
∴ R = (0.2 + 0.2 + 0.2 + 0.2 + 0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2)/10
R = 0.2 Ω
