Consider the following figure. C₁ C₂ a C₁ C3 C₂ C₂ (a) Find the equivalent capacitance between points a and b for the group of capacitors connected as shown in the figure above. Take C₁ = 4.00 μF, C₂ = 15.0 μF, and C3 = 3.00 μF. Try redrawing the circuit sliding capacitors C₁ and C₂ on the left and right halves of the upper loop towards the outside so that they reside on the vertical segment of conducting wire. Note that sliding a capacitor along a conducting wire does not affect the circuit as long as you do not pass a junction with another wire. µF (b) What charge is stored on C3 if the potential difference between points a and b is 60.0 V? Your response differs from the correct answer by more than 10%. Double check your calculations. μC

A C1 +47 C2 B C3 C4 The circuit shown above has capacitors in a network. If C1 is 0.938 F, C2 is 0.329 F, C3 is 0.808 F, and C4 is 0.307 F, what the capacitance of the entire circuit (as measured between A and B)? Report your answer to three significant digits.

Consider the circuit shown in the figure below. The four capacitors have capacitances C1=15µF, C2=14µF, C3=52µF, C4=18µF and are connected to a battery of voltage V=33Volts. When all capacitors are fully charged, determine the charge on C4. Express your answer in units of pF using zero decimal places. C2 C3 C1 C4 V

For the circuit shown, AVbattery = 28 V, R₁ = 5.0 02, R₂ = 5.0 2 and C= 4.5 F. The capacitor is initially uncharged and the switch is open. What is the charge on the capacitor a long time after the switch is closed, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R₁ www R₂ www C
