Question : 27
Total: 27
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 given below:
Plot a graph between current (I) and potential difference ( V )
| V (volts) | | | | | | | | |
|---|---|---|---|---|---|---|---|---|
| I (amperes) | | | | | | | | |
Solution:
We know that, V = ℝ V = 0.5
I = 0.1
0.5 = 0.1 × R
= R
R = 5 Ω .
From the graph,
