RE-NEET 2024 Physics Capacitance MCQ Question

Chapter: Electrostatic Potential and Capacitance

Class: 12 Physics — Chapter 2

Topic: Capacitance Difficulty: 🟢 Easy

✅ Ans: B — Geometry of the capacitor

For a parallel-plate capacitor:

$$C=\frac{\varepsilon_0 A}{d}$$

So capacitance depends on:

• Area of plates $A$
• Separation $d$
• Dielectric medium

It does not directly depend on $q$ or $V$ because:

$$C=\frac{q}{V}$$

📌 NCERT: Capacitance is determined by the geometry of the capacitor and dielectric material.

🧠 NEET Trick: $q$ and $V$ can change, but $C$ remains fixed unless geometry/dielectric changes.
