Question 6 A capacitor consists of two similar square aluminium plates, each 10 cm x 10 cm mounted parallel and opposite to each other. What is their capacitance when the distance between them is 1 cm and the dielectric is air? If is the capacitor is given a charge of 500 PC, what will be the difference of potential between plates? How will this be affected i the space between the plates is filled with wax which has a relative permittivity of 4?
