Dielectrics, Capacitor Types and Uses

Physics · Class 12

A dielectric is an insulating material that can become polarized in an electric field and can increase the capacitance of a capacitor.

κ=C/C₀
C=κC₀
C=κε₀A/d
Capacitor Types: When a dielectric is placed between capacitor plates, its atoms or molecules become polarized. Boun
Uses: Capacitors are used for: temporary energy storage; filtering; smoothing; timing circuits; *
Dielectrics increase capacitance by polarization.
