electrostatic-potential-and-capacitance Question 45

Question: Q. 19. The following graph shows the variation of charge $Q$ with voltage $V$ for two capacitors $K$ and $L$ in which capacitor is more electrostatic energy stored?

C] [Foreign 2008]

Show Answer

Solution:

Ans. The slope of $Q - V$ graph of capacitor gives capacitance, therefore, capacitor $Δ$ have greater capacitance. Since, two capacitors are given same voltage $V$ , therefore energy stored in a capacitor will be given by formula.

$\begin{array}{ll} ∵ & C_{L} > C_{K} \Rightarrow & U_{L} > U_{K} \end{array}$

$\Rightarrow$ Capacitor $L$ with store more electrostatic energy.
