... The output voltage from a typical energy source stays the same regardless of its output current (I) so long as it is less than the sources’ rated current value. Within this range, the output current (I) only depends on the resistance (R) of the equipment (i.e., the load) connected to the source. I ...

... phenomenon. It is clear, however, that non-ordinariness of the phenomenon would require a non-ordinary approach to its explanation. At present, we can speak about two qualitative models. The first model implies the existence of an external cosmo-physical factor [2, 4, 5, 8], affecting physical proce ...

Superposition

... 1. Superposition only works with linear circuits. (Linear circuits contain only sources, resistors, capacitors, inductors, linear amplifiers, etc.) Most electronic devices (diodes and transistors) are non-linear, so superposition will not be applicable. 2. Because the method relies on linearity, you ...

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.
