2. A 15-MΩ resistor and a 48-nF capacitor get connected in series to a 15-V battery. a. How long will it be until the capacitor is “fully” charged? b. If the battery is then disconnected from the circuit, how long will it be until the capacitor’s voltage is 9.0 V? What is the charge of the capacitor at that moment? c. If we’d like the capacitor’s voltage in this circuit to decrease from 15-V to 9.0-V in 1.5 seconds after the battery gets disconnected, how should the capacitance of the capacitor change (increase or decrease, and by how much)?
