Practical Capacitors There are a wide variety of capacitor types which use a number of different construction materials. Here is a broad selection of the ind of thing that is available. Capacitor Types Fixed Values Ceramic Disc Made by coating a ceramic disc with silver contacts on both sides. To make larger value capacitors they […]
Inductors Electromagnetism – A Quick Introduction An electromagnetic field is the combination of both an electric field and a magnetic field. Both affect each other and both always exist whenever there is a moving electrical charge. However, both can also exist independently of each other (think static electricity and a bar magnet). Electricity to Magnetism […]
Series & Parallel Inductors You may still be reeling from the strange complications of calculating series and parallel capacitors and voltage/current dividers. I am happy to report that there are no such issues with inductors. To all intents and purposes, inductors can be treated in the same way as resistors! Series Inductors Series inductances are […]
Practical Inductors Before looking at a few of the many types of inductors a few properties of real world inductors should be kept in mind: Inductor Types Air Core Arguably the simplest of all deliberately made inductors. For R.F. applications may be as simple as a single turn wound around a former, such as a […]
