Internal Resistance and Resistivity in DC Circuits
Internal Resistance and Resistivity in DC Circuits

... Resistivity All wires in a circuit also contribute to the overall resistance in a circuit. Even though the value is often small and negligible, it is often important to determine the value for the resistance of a wire if it is thick or long. This being said, the resistance is dependant on the geome ...

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.
