What will be the effect on capacity of a parallel plate condenser when area of each plate is doubled and distance between them is also doubled?

---

Capacitance is given by-C=$\frac{{\epsilon }_{\circ }A}{d}$
where, A is the area of cross-section,
d is the distance between two plates.

When, area of each plate is doubled and distance between them is also doubled,
Capacitance-C=$\frac{{\mathrm{\epsilon }}_{\circ }2\mathrm{A}}{2\mathrm{d}}$

The factor 2 cancels out each other. This implies, capacitance remains unaffected.
