Plate Geometry EffectHardQuestion 31516

Question

Two square plates of side 10 cm each are separated by 1 mm. Approximate capacitance (ε₀ = 8.85×10⁻¹² F/m) is:
  1. A
    88.5 pF
    Correct
  2. B
    8.85 pF
  3. C
    885 pF
  4. D
    0.885 pF

Correct answer

88.5 pF

Explanation

C = ε₀A/d = 8.85×10⁻¹² × 0.01/0.001 = 88.5 pF.
