How to Make Capacitors - Low Voltage Homemade/DIY Capacitors

A variety of info on how to make low voltage capacitors. I start with demonstrating making a temporary flat plate capacitor, then a spiral capacitor and then a salt water jar capacitor, sometimes called a salt water Leyden jar. Then I talk about capacitance and the unit farad and show the difference between microfarad, nanofarad and picofarad. Next, using the formula for a flat plate capacitor as a base I discuss the affect of capacitor area and distance between the plates on the capacitance. I also go over the dielectric constant, sometimes called the relative permittivity, and end with the formula for a cylindrical capacitor. All this is to help in designing capacitors. I then show how to use a meter, DMM, to measure capacitance. That's followed by two sample variable capacitors and then a discussion about breakdown voltage, or dielectric strength.
