This physics video tutorial provides a basic introduction into dielectrics and capacitors. It explains the effect of adding an insulator with a dielectric constant higher than air to a capacitor. Increasing the dielectric constant K causes the capacitance to increase and the voltage & electric field to decrease proportionally. This tutorial contains plenty of examples and practice problems on dielectrics and capacitors.
