In the animation below, a parallel-plate capacitor is connected in series with a battery and a switch. Blue dots are arranged within the conducting plates and connecting wires with spacing that indicates a surplus (close spacing) or deficit (wide spacing) of electrons. The net charge on each capacitor plate is also indicated with color. Instructions: Use the slider to adjust the battery voltage and close switch S to charge the capacitor. You may click the switch open at any time. Explore Click "reset", open switch S, then adjust the voltage slider to 4 V. Close the switch, and observe what happens to the conduction electrons. As the capacitor charges, you should notice the following: 1. The number of electrons increases on the plate attached to the negative pole of the battery. 2. The number of electrons decreases on the positive plate. 3. As the capacitor charges, the electric field between the capacitor plates increases. The electric field strength is indicated by the horizontal arrows. The magnitude of the electric field is indicated by the number of arrows. With switch S still closed, increase the voltage to 10 V, and observe the charge carriers as they redistribute. What happens when you decrease the voltage? Note: as the capacitor charges, electrons do move through the battery (this is not indicated by the blue dots in the animation). An analogy might be useful: a battery is to current flow as a pump is the fluid flow. The battery causes charge carriers to move to new locations in the circuit. As the capacitor charges, electrons move from the positive plate to the negative plate. In order to do this, they must flow through the circuit. Thus, electrons do not move "across the gap" in the capacitor. They must move along the circuit in a path that leads through the battery. Suppose the capacitor is discharging. Select all statements below that are true. The number of electrons on the negative plate is increasing. The number of electrons on the positive plate is increasing. The number of electrons on the positive plate is decreasing. The electric field between the plates is increasing. The number of electrons on the negative plate is decreasing. The electric field between the plates is decreasing.
