Class 12PhysicsElectric Potential and CapacitanceBasic of Capacitor and type of capacitor (Spherical, Cylindrical)
EasyThe graph shows the variation of voltage $V$ across the plates of two capacitors $A$ and $B$ versus the charge $Q$ stored in them. Then:
- ACapacitor $A$ has higher capacitance.
- BCapacitor $B$ has higher capacitance.
- CBoth have the same capacitance.
- DCapacitance of $A = 2$ times capacitance of $B$.
