Is it true that a dielectric increases capacitance in a capacitor?
Yes. A textbook and a physics derivation state directly that placing a dielectric between capacitor plates increases capacitance, and a further answer generalizes this to all capacitor types. Other sources show dielectric changes affecting capacitance in narrower settings such as nanoscale models and MOSFET gate films.
