If both the plate area and the plate separation of a parallel-plate capacitor are doubled, the capacitance is:
A) doubled
B) halved
C) unchanged
D) tripled
E) quadrupled

Question

Quizplus · Accepted Answer

The capacitance of a parallel-plate capacitor is given by the formula C = ε₀(A/d), where A is the plate area and d is the separation between the plates. If both A and d are doubled, the changes cancel each other out, leaving the capacitance unchanged.

If Both the Plate Area and the Plate Separation of a Parallel-Plate
