The graph shows the variation of potential difference between the plates of two capacitors A and B with the increase of charge stored by them. From the graph we can conclude:
- A Capacitance of A is greater than B
- B Capacitance of B is greater than A
- C B stores more electrostatic energy than A at a given potential
- D A stores more electrostatic energy than B at a given charge
Answer & Solution
Correct Answer
(A) Capacitance of A is greater than B
Step-by-step Solution
Detailed explanation
\( \text{Slope of V-Q graph} = \frac{\Delta V}{\Delta Q} = \frac{1}{C} \). From the graph, Slope\(_{\text{A}}\) > Slope\(_{\text{B}}\). \( \frac{1}{C_A} > \frac{1}{C_B} \). \( C_B > C_A \).
