Question: A 1.05 µF capacitor initially charged to 10.5 V, discharges when it is connected in series with a resistor.
Part I: What resistance is necessary to cause the capacitor to have only 37% of its initial charge 1.70s after starting?
Part II: What is the voltage across the capacitor at t = 5 second if the capacitor is instead charged by the same battery through the same resistor?
Show the each step of calculation in detail.
