Question
Three V-I graphs are drawn individually for two resistors and their series combination. out of A, B, C which one represents the graph for series combination of the other two? Give reason for your answer.
✓

Answer

We Know that $\text{V} = \text{IR}$

And resis tan ce $\text{R} = \frac{\text{V}}{\text{I}}$

$\frac{1}{\text{R}}= \frac{\text{dI}}{\text{dV}}=$ slop, which is ,maximum for C

So the resis tan ce will maximum for A, so A show the series combination of the B and C because the net resi tan in series combination is always greater than the individual resistors.
