... When the points break the circuit to earth, this stops the 10v flow and the magnetic field collapses. This is instantly converted to the large 20,000v which travels thru heavier wiring via the distributor to the spark plug. With starter-motor engaged, there may only be 7volts available to flow to th ...

... We define the efficiency of a power supply to be the ratio of the output power to the input power. It’s interesting to find the efficiency of this simple AC to DC converter. Finding this efficiency does require a few circuit modifications. The modified circuit is shown in Figure 9. The output power is relativ ...

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.
