Part A: Capacitors #1. In the following figure, the battery has a potential difference of V=100.0 V and the five capacitors each have a capacitance of 22.0 uF. What is the charge on (a) capacitor 1 and (b) capacitor 2? #2. A parallel-plate air-filled capacitor having area 40 cm and plate spacing 1.0 mm is charged to a potential difference of 500 V. Find (a) the capacitance, (b) the magnitude of the charge on each plate, (c) the stored energy, (d) the electric field between the plates, and (e) the energy density between the plates. # 3. A capacitor of unknown capacitance C' is charged to 100 V and connected across an initially uncharged 60 F capacitor. If the final potential difference across the 60 F capacitor is 40 V, what is C? #4. The following figure shows a parallel-plate capacitor filled with three different dielectrics. (a) Derive an equation to find the capacitance of the capacitor. (b) If the capacitor has a capacitance of 10 nF without the dielectrics, calculate its capacitance when K = 10, K = 20 and K3 = 60.
