Practicing Success
A capacitor is a system of two conductors separated by an insulating medium. Capacitance of this systems is determined purely geometrically, by the shapes, size and relative position of the conductors. The medium between the two conductor can be air or a dielectric. The way the dielectric is inserted accordingly by capacitance changes. Electric energy is stored in the capacitors. The capacitor can be connected in series or in parallel in an electric circuit. |
Given below are two statements. Statement I: Equivalent capacitance of a series combination of three capacitors will always be greater than any individual capacitance connected in series. Statement II: When a series combination of three capacitors is connected across a voltage source, magnitude of charge stored on each plate of all the three capacitors is the same. In the light of the above statements, choose the correct answer from the options given below: |
Both statement I and statement II are true Both statement I and statement II are false Statement I is correct but statement II is false Statement I is incorrect but statement II is true |
Statement I is incorrect but statement II is true |
The correct answer is Option (4) → Statement I is incorrect but statement II is true In series combination, Net capacitance < Capacitance of any individual capacitor. But, In series combination charge stored on each capacitor is same ∴ Statement I is incorrect While statement II is correct |
