ideal voltage and current sources

... The first stage of a rigorous solution is to calculate the voltage V across the 4IΩ resistance. Using Kirchhoff’s Voltage Law around the closed circuit loop: VI-I8I=I0, and therefore V = 8 V. The current I flows from the source into the resistance in a direction consistent with Ohm’s Law, so I = 8 / ...

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.
