Abstract
Free oscillation in a circuit is generally short-lived because of the presence of a resistance. NormallyACcurrent flows continuously, as the generator keeps supplying energy, but it is not simple to obtain a source of persisting electrical oscillations at a desired frequency. Today, vacuum tubes and semi-conducting devices, oscillators, signal amplifiers, and other electronically controlled circuits are available at almost any frequency, thereby, basic electromagnetic experiments can be performed with precision in modern electronics. A self-sustaining oscillator with a sizable output power is a particularly important device to study high-frequency phenomena.
