Capacitance is given by:
Correct answer: A. C = εₒA/d
- A. C = εₒA/d
- B. C = dA/εₒ
- C. C = d/Aεₒ
- D. C = dεₒ/A
Explanation
The capacitance of a parallel plate capacitor is directly proportional to the area of the plates (A) and the permittivity of free space (εₒ). It is inversely proportional to the distance (d) between the two plates. Hence, capacitance is given by: C = εₒA/d.

About Capacitors
Capacitors store electric charge and energy in an electric field between conductors. Work includes capacitance, the relation Q = CV, dielectric materials, charging and discharging, energy formulas, and combinations of capacitors in series and parallel. Electric potential difference is needed to understand why charge and stored energy change.
