Question 1
2021 Paper 5
2For changing the capacitance of a given parallel plate capacitor, a dielectric material of dielectric constant is used, which has the same area as the plates of the capacitor. The thickness of the dielectric slab is , where ' ' is the separation between the plates of parallel plate capacitor. The new capacitance ( ) in terms of original capacitance is given by the following relation :Tap an option to check your answer.
