Q2 (40P). Consider you have a capacitor (C1=10 pF) which is initially uncharged. Then, it is connected to a battery having 100 V potential difference. After fully charging of this capacitor, disconnect the battery from the capacitor and connect another uncharged capacitor (C23D0.2 uF) to the charged capacitor's terminals. a) Calculate the charge of the capacitor in the first circuit, b) Calculate the potential difference across each capacitor when both are connected together, c) Calculate the energy of the system (combination of two capacitors), d) Calculate the first circuit's energy and compare it with the final situation. Have you found a decrease or increase in energy when the second capacitor is connected? Comment and explain the physical meaning of this decrease or increase in energy with your own sentences.
