Answer to Question #73805 in Electric Circuits for Akash Kumar kheti
A parallel plate capacitor is made of two rectangular aluminium sheets of lateral
dimensions 500 mm and 20 mm. The space between the plates is filled with polystyrene and the separation between plates is 0.15 mm. Calculate the capacitance
of the capacitor and the value of the maximum potential difference that can be
applied across the capacitor without dielectric breakdown. Take the dielectric
constant of polystyrene as 2.6 and the value of the maximum electric field that
polystyrene can withstand as 25×106 Vm−1 .
