Capacitor

The capacitance of a parallel plate capacitor with air as medium is \(3 \mu \mathrm{F}\). With the introduction of a dielectric medium between the plates, the capacitance becomes \(15 \mu \mathrm{F}\). The permittivity of the medium in \(\mathrm{SI}\) unit is \([\varepsilon_0=8.85 \times 10^{-12} \mathrm{SI}\) unit]
