A10 M? resistor is connected in series with a 1 μF capacitor and a 12 V battery. When the circuit is connected the capacitor begins to charge. a) At what time will the capacitor have a 0.2μC charge? b) What is the current at this time? c) What is the potential difference across the resister at a time of 2 s? d) What is the potential difference across the resister at a time of 10 s?
