How can we decrease the effective capacitance of a parallel plate capacitor?
How can we decrease the effective capacitance of a parallel plate capacitor?
Show Hint
To decrease the capacitance of a parallel plate capacitor, increase the distance between the plates, as capacitance is inversely proportional to this distance.

- Increase the distance between the plates
- Decrease the distance between the plates
- Increase the area of the plates
- Increase the dielectric constant

The Correct Option is A
Solution and Explanation
The capacitance \( C \) of a parallel plate capacitor is given by:
\[
C = \frac{\varepsilon_0 A}{d}
\]
Where:
- \( \varepsilon_0 \) is the permittivity of free space,
- \( A \) is the area of the plates,
- \( d \) is the distance between the plates.
From this formula, we can see that the capacitance is inversely proportional to the distance between the plates. Therefore, to decrease the capacitance, we can increase the distance between the plates.

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :
