ENGAGEMENT Problem Set: Solve the following. SHOW YOUR SOLUTION and BOX YOUR FINAL ANSWER. 1. In open heart surgery, a much smaller amount of energy will defibrillatorhe heart. (a) What voltage is applied to the 8.00 uF capacitor of a heart defibrillator that stores 40.0 J of energy? (b) Find the amount of stored charge. 2. Suppose you have a 9.00 V battery, a 2.00 uF capacitor, and a 7.40 uF capacitor. (a) Find the charge and energy stored if the capacitors are connected to the battery in series. (b) Do the same for a parallel connection. 3. Find the total capacitance shown on the figure below. 0.30 UF 2.5 ULF 10 UF 4. A capacitor filled with air is formed by two spherical shells with inner radius 1 cm, and outer radius 5 cm. What is its capacitance? 5. A Cylindrical capacitor having a length of 8 cm is made of two concentric rings with an inner radius as 3 cm and outer radius as 6 cm. Find the capacitance of the capacitor. 6. A parallel-plate capacitor is filled with polystyrene of 0.0002 m thickness. Find the plate area if the new capacitance after the insertion is 3.4 uF
