Electricity – Electric Circuits

... In metals, some electrons (which are negatively charged) are free to move between the atoms. These are called free electrons and are why metals are good conductors of electricity. Covalent solids, such as plastic, do not contain free electrons and so are poor conductors of electricity. These are cal ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
