A parallel plate capacitor of capacitance 1 mu F is to be formed with the insertion of mica plates, each of thickness 0.5 mm, between two consecutive metal plates. How many metal plates, each of radius 2 cm, are to be used? The metal plates are altermately connected among themselves.

A parallel plate capacitor is constructed using three different dielectric materials as shown. br> Find the equivalent capacitance.

A parallel plate capacitor has two plates of dimensions 10 cm xx 7 cm separated by a distance of 0.7 mm. A glass plate of thickness 0.4 mm (dielectric constant = 6) and another dielectric medium of thickness 0.3 mm (dielectric constant = 2.5) are placed between the plates of the capacitor. Calculate the capacitance of the capacitor before and after introduction of the dielectric media.
