  2. 1 of 3 • Which system has greater capacitance? • A (press 1). • B (press 2). • Both have same capacitance. • Cannot be determined without specifying the source of EMF. B A POSITIVE PLATE POSITIVE PLATE VACUUM PAPER NEGATIVE PLATE NEGATIVE PLATE 2

  3. 2 of 3 • Which two-capacitor system has greater capacitance? • A (press 1). • B (press 2). • Both have the same capacitance. • Cannot be determined without specifying the source of EMF. B A 1000 pF 1000 pF 1000 pF 1000 pF 3

  4. 3 of 3 • The capacitor C is charged initially with charge Q. After S1 is closed, the current through the resistor will • Start out small and get bigger for a while, but become steady. • Start out at a certain amount, and stay that way (steady current). • Start out big, but get smaller and smaller over time.
