A bаttery is cоnnected tо the cаpаcitоr circuit shown below providing a potential difference of 215 V. The capacitor values are all in microfarads. a) Find the equivalent capacitance for the capacitor circuit. b) How much energy is provided by the battery for the capacitors in this circuit? c) Calculate the charge on the 222 mF capacitor. d) What is the potential difference across the 57 mF cap? e) Calculate the energy stored by the 107 mF capacitor. part a) 4. The proper combinations are circled below. Write the equivalent capacitance for each circled combination . Do not include units and round to 3 decimal places. What is the equivalent capacitance for combination B? CBeq = .
Cоnsider the cоncentric sphericаl cоnductors аrrаnged as shown in the figure below. Each of the dimensions for the conductors are given in terms of the length a. Assume the cavity between the conductors is initially a vacuum. Clearly justify all of your answers to the following questions. a) Calculate the capacitance for the arrangement of conductors shown in the figure. Your answer should be written in terms of a number and a. b) For the rest of this problem use a = 0.0022 m. Calculate the capacitance of the spherical conductors for a = 0.0022 m. c) A 28 V battery is connected between the inner and outer conductors. How much charge develops on each of the conductor surfaces? While the battery is connected to the capacitor, the vacuum seal starts to leak filling the cavity with a gas that increases the permittivity to 2.08x10-10 C2/Nm2. Answer the following questions concerning the effect of the dielectric. d) How much energy is stored by the capacitor with a dielectric? e) What is the new charge on the conductors? f) Now the battery is disconnected from the capacitor. If the dielectric gas is removed from in between the conductors, then calculate how much energy is now stored by the capacitor? part a) 2. After putting a charge on the inner and outer conductors, how would you calculate the electric field between the inner and outer conductors?

If the dielectric gas is removed from in between the conductors, then calculate how much energy is now stored by the capacitor? part a) E = 8.992 x109 4. Now calculate the potential difference between the inner and outer conductors. Your answer should be a number times Q/a, so just put the number in scientific notation and type in the coefficient, rounding to 3 decimal places. Take the absolute value so you have a positive number.
