Question

In a parallel-plate capacitor, the distance d between the plates is 3cm, the area of each plate is 15cm², and the voltage across them is 5V. Calculate the capacitance. (ε₀ = 8.854×10^-12 C/Nm²)
Options
A 3.33×10^-13 F
B 9.31×10^-11 F
C 4.43×10^-13 F
Correct Answer
D 1.29×10^-12 F
Correct Answer

Option C is the correct answer.

Detailed Explanation

A = 15×10^-4 = 1.5×10^-3 m². C = ε₀A/d = 8.85×10^-12 × 1.5×10^-3 / 0.03 = 4.43×10^-13 F.

Hint

Use C = ε₀A/d.
