Electrostatic Potential And Capacitance

Question

Wired Faculty App

The given graph shows the variation of charge q versus potential difference for 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 corresponds to C₁ and C₂ and why?

Solution

Capacitance of the parallel plate capacitor -C=

\frac{ε_{\circ} A}{d} \propto A

Given, the plate area of C₂ is double than that of C₁.
C₂=2C₁
Slope of Q-V graph represents Capacitance C.

Here, the slope of A is greater than slope of B.

Hence, line A represents C₂and line B represents C₁.
