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: |
Capacitance of A is greater than B Capacitance of B is greater than A B stores more electrostatic energy than A at a given potential A stores more electrostatic energy than B at a given charge |
Capacitance of A is greater than B |
The correct answer is Option (1) → Capacitance of A is greater than B Relation between charge and potential difference: $Q = CV \quad \Rightarrow \quad V = \frac{Q}{C}$ In $V$–$Q$ graph, slope = $\frac{V}{Q} = \frac{1}{C}$ From the graph, slope of B is greater than slope of A. $\Rightarrow \frac{1}{C_B} \gt \frac{1}{C_A} \quad \Rightarrow \quad C_A \gt C_B$ Therefore, capacitance of A is greater than capacitance of B. |
