Problem 5 A capacitor consists of two parallel plates separated by a dielectric of * = 4. With the dielectric the C capacitance of the capacitor is C = 400 nF (nano = 10-9). KC The capacitor is always connected to a 1000 V battery for all the following questions. (a) [2 points] Determine the amount of energy stored in the capacitor. While connected to the battery the dielectric is removed from the capacitor. (b) [3 points] How do the voltage, charge, and capacitance change? Remains Increases Decreases the same V O C (c) [3 points] How much work was required to remove the dielectric from between the plates
