If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...

The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

Another passive two-terminal electrical component is the capacitor. It is formerly known as a condenser and is capable of storing energy in the form of an electrostatic charge that produces a ...
