Try to find the definitions for those variables and see if you can figure out how to apply them in this situation.In summary, the conversation discusses the assembly of a homemade capacitor using two pie pans and a 9V battery. The capacitance, charge on each plate, electric field, and work done by the battery are estimated and equations for calculating the capacitance of a parallel plate capacitor are provided. The conversation ends with a suggestion to reread the textbook for more information on capacitors and Gauss' law.

What's the capacitance of a parallel-plate capacitor?
 
  • #4
Yes, so you should be able to calculate the capacitance of the homemade capacitor, which is essentially two parallel plates.
 
  • #5
Can you point of which formula(s) i should use? Thanks
 
  • #7
What does A or D refer to? and What is the Epslion number?
 
  • #8
I think you need to reread the chapter in your textbook about capacitors (and possibly the chapter about Gauss' law).
 

FAQ: How Do You Solve Homemade Capacitor Problems?

What is a homemade capacitator?

A homemade capacitator is an electronic component that stores and releases electrical energy. It is used in various electronic devices to regulate the flow of electricity.

How do I make a homemade capacitator?

To make a homemade capacitator, you will need two conductive plates, an insulating material, and a power source. Place the insulating material between the two plates and connect the power source to the plates. This will create a basic capacitator.

What are the benefits of using a homemade capacitator?

Using a homemade capacitator allows you to create a customized capacitator for your specific needs. It can also be a cost-effective alternative to purchasing a pre-made capacitator.

Can I use any materials to make a homemade capacitator?

While there are many different types of capacitators, not all materials are suitable for making a homemade capacitator. It is important to use materials that are conductive and insulating in order for the capacitator to function properly.

Are homemade capacitators safe to use?

As with any electronic device, there are certain safety precautions that should be taken when using a homemade capacitator. Make sure to use appropriate materials and follow proper instructions to avoid any potential hazards. It is also important to handle the capacitator with caution, as it can store a significant amount of electrical energy.
