List of vacuum tubes — This is a list of vacuum tubes or thermionic valves. Before the advent of semiconductor devices, hundreds of tube types were used in consumer and industrial electronics; today only a few types are still used in specialized applications. Contents… … Wikipedia
Lecher lines — are a form of parallel conductor that can be used at UHF for creating resonant circuits. They are used at frequencies between HF/VHF where lumped components are used, and UHF/SHF where resonant cavities are more practical. Ernst Lecher of Vienna … Wikipedia
Auxiliary electrode — The Auxiliary electrode, often also called the counter electrode, is an electrode used in a three electrode electrochemical cell for voltammetric analysis or other reactions in which an electrical current is expected to flow.[1][2][3] The… … Wikipedia
Nitrogen Phosphorus Detector — The nitrogen phosphorus detector (NPD) is a form of gas chromatography in which thermal energy is used to ionize an analyte. With this method, nitrogen and phosphorus can be selectively detected with a sensitivity that is 104 times greater than… … Wikipedia
Electrical polarity — (positive and negative) is present in every electrical circuit. Electrons flow from the negative pole to the positive pole. In a direct current (DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in … Wikipedia
Topfkreis — Ein Topfkreis ist ein allseitig geschlossener koaxialer Leitungskreis, der sich wie ein Parallelschwingkreis verhält[1]. Im Gegensatz zu einem Schwingkreis aus diskreten Bauteilen ist seine Resonanzfrequenz nicht eindeutig, da die… … Deutsch Wikipedia
