The graph shows the variation of voltage (v) across the plates of two parallel plate capacitors A and B versus increase of charge Q stored in them. Then
Options
- Acapacity of both capacitors is same.
- Bcapacity of A is higher than B .
- Ccapacity of B is higher than A .
- Dcapacity of both is zero.
Correct answer
B. capacity of A is higher than B .
Step-by-step solution
The relationship between charge and voltage for a capacitor is given by Q = CV , which rearranges to V = 1 C Q . Comparing this with the standard linear form y = mx , the slope of the V-Q graph equals 1 C . Since capacitor B's graph has a steeper slope than A's, we have 1 C_B > 1 C_A , and thus C_B Therefore, capacitor B has smaller capacitance than capacitor A. Final answer: B
