The graph shows the variation of voltage ' V ' across the plates of two capacitors A and B versus increase in charge ' Q ' stored in them. Then (a) capacitance A has high capacity. (b) capacitance B has high capacity. (c) both have same capacity. (d) capacity of A = 2 times capacity of B.

Answer: (a). For a capacitor V = Q/C, so the slope of the V – Q line is 1/C. For the same Q, VA CB. So the answer is (a) capacitor A has the higher capacity.

Capacitance of a Conductor

The graph shows the variation of voltage ' V ' across the plates of two capacitors $A$ and $B$ versus increase in charge ' $Q$ ' stored in them. Then

Show answer and solution

Answer: (a)

For a capacitor $V = \frac{Q}{C}$ , so the slope of the $V$ – $Q$ line is $\frac{1}{C}$ .
For the same $Q$ , $V_A < V_B$ , so line A has the smaller slope.
Smaller slope means larger capacitance: $C_A > C_B$ .
So the answer is (a) capacitor A has the higher capacity.
