Parallel Plate Capacitor question from NEET 2022 (Phase 2)

Q9NEET 2022 · PHASE 2Easy

Parallel Plate Capacitor

The distance between the two plates of a parallel plate capacitor is doubled and the area of each plate is halved. If C is its initial capacitance, its final capacitance is equal to

Show answer and solution

Answer: (a)

$C = \frac{\varepsilon_0 A}{d}$
$C' = \frac{\varepsilon_0 (A/2)}{2d} = \frac{C}{4}$
So the answer is (a) $\frac{C}{4}$ .
