6 FAQs about [Experimental questions on circuits with capacitors]

What do you learn in a capacitor lab?

In this part of the lab you will be given 3 di erent capacitors, jumping wires, a breadboard, a multimeter and a capacimeter. You will investigate how capacitors behave in series and parallel and how voltages are distributed in capacitor circuits. With the given materials, complete the following tasks:

What happens when a capacitor is charged to a maximum Q?

Once charged to its maximum possible Q, the capacitor's plates are separated by a factor of four (that is, the distance between the plates is quadrupled) while the capacitor is kept hooked to the power supply. As a consequence of this change in geometry:

What happens if a capacitor accumulated a long period of time?

Solution: After a long period of time, the accumulated charge on the capacitor's plates will produce a voltage across the capacitor that is equal to the voltage across the power supply. At that point, there will no longer be current in the circuit.

What is a simple capacitor?

A simple capacitor is the parallel plate capacitor, represented in Figure 1. The plates have an area A and are separated by a distance d with a dielectric ( ) in between. The plates carry charges +Q and Q, respectively, on their surfaces. The capacitance of the parallel plate capacitor is given by

What is the relationship between charge Q and voltage VC?

Solution: The relationship between the charge q on the capacitor at any time and the voltage Vc across the capacitor at that time is q = CV. When the capacitor is fully charged, the voltage across the capacitor will equal the voltage across the power supply, and we can write q = (10-6 f)(100 volts) = 10-4 coulombs. e.)

What happens if a capacitor is completely charged?

Solution: When the capacitors are totally charged, there will be no current through the circuit (the charged capacitors will act as open circuits). That means the ENTIRE 120 volt voltage drop will be across EACH parallel capacitor. Q6 = C6Vo = (6 x10-6 f)(120 volts) = 7.2 x10-4 coulombs.
