Find the potential difference of point relative to point Question 5 Learning Goal: To study the behavior of a circuit containing a resistor and a charged capacitor when the capacitor begins to discharge. C q. t=0, A capacitor with capacitance is initially charged with charge At time a switch is thrown to close R. the circuit connecting the capacitor in series with a resistor of resistance (Figure 1) Part A What happens to the charge on the capacitor immediately after the switch is thrown? What happens to the charge on the capacitor immediately after the switch is thrown? The electrons on the negative plate of the capacitor are held inside the capacitor by the positive charge on the other plate. Only the surface charge is held in the capacitor; the charge inside the metal plates flows through the resistor. The electrons on the negative plate immediately pass through the resistor and neutralize the charge on the positive plate. The electrons on the negative plate eventually pass through the resistor and neutralize the charge on the positive plate. Part B This question will be shown after you complete previous question(s). Question 6 Learning Goal: To learn to calculate the equivalent resistance of the circuits combining series and parallel connections. Resistors are often connected to each other in electric circuits. Finding the of equivalent resistance combinations of resistors is a common and important task. Equivalent resistance is defined as the single resistance that can replace the given combination of resistors in such a manner that the currents in the rest of the circuit do not change. Finding the equivalent resistance is relatively straighforward if the circuit contains only series and parallel connections of resistors. An example of a series connection is shown in the diagram:
