Capacitance of a capacitor depends on the size and shape of the conductors and on the dielectric mate rial between them.: Draw the symbol of a variable capacitor.

Derive an expression for capacitance of the above capacitor with the dielectric slab in between the plates

A dielectric slab is placed between the plates of a parallel plate capacitor. Its capacitance.

How capacitance changes if the distance between the plates of a parallel plate capacitor is halved?

A dielectric is placed in between the two parallel plates of a capacitor is shown in figure. The dielectric constant of the dielectric is K. If the initial capacitance is C, then the modified capacitance will be
