i. A parallel plate capacitor has two square plates of side length L, and the plates are separated by distance d. How would the capacitance change if the side length of the plates doubled? ii. How would the capacitance of the above capacitor change if the separation distance between the plates doubled? iii. If I insert a dielectric material of dielectric constant κ>1 between the plates of the capacitor (there was only air there before), does the capacitance increase, decrease, or stay the same?
Batteries and capacitors can be used to store electrical energy. Batteries do this in the form of chemical potential energy whereas capacitors do this with an electric field. Batteries tend to be more stable but capacitors tend to have faster charge and recharge times. A simple capacitor can be constructed from two conductive plates. Two conductive plates with an area of 10.0cm x 10.0 cm are held facing one another at a separation of 1.50 mm and 12.0 V is applied between them. a) Find the capacitance of this configuration b) Find the charge on the plates. c) How much energy is stored in the capacitor? d) How much energy can the capacitor store if a dielectric with K= 4.5 is inserted between the plates rather than air?
