A "sandwich" is constructed of two flat pieces of metal (0.70 cm on a side)with a 1.0-mm-thick piece of a dielectric called rutile (κ = 100)in between them.What is the capacitance? (ε₀ = 8.85 × 10−¹² C²/N⋅m²)

Question

Quizplus · Accepted Answer

The capacitance C is given by the formula C = κε₀A/d, where κ is the dielectric constant, ε₀ is the permittivity of free space, A is the area, and d is the separation distance. Substituting the given values, C = 100 * 8.85 × 10⁻¹² * (0.007 * 0.007) / 0.001 = 43 pF.
