The given graph shows the variation of charge q versus potential difference of two capacitors C1 and C2. The two capacitors have same plate separation, but the plate area of C2 is double that of C1.Which of the lines in the graph correspond to C1 and C2 and why?

Answer»

As,

C = \(\frac{∈_0A}{d}\) and 

plate area of C2 is double than that of C1

Therefore, 

C2 >C1 

Now, 

C = \(\frac{q}{V}\), which is greater for line A. 

∴ The line A of the graph corresponds to C2 and line B corresponds to C1.
