Electrical Engineering XYZ MCQs
Capacitance is directly proportional to:
- Plate area
- Spacing between plates
- Both of these
- None of above
Correct answer: 1. Plate area
Explanation: Capacitance in a capacitor is directly proportional to the area of the plates. This means that if you increase the size of the plates, the capacitance will also increase. Capacitance is not directly proportional to the spacing between the plates; in fact, it’s the opposite. Increasing the space between the plates actually decreases the capacitance. Therefore, only the plate area affects the capacitance in a directly proportional way.
