The first shows the anode tied to ground through R1 and the cathode tied to the Vcc power rail. The diode is in reverse bias, and no current is flowing through it. An AC voltage applied to C1 will ...

Then knowing he needed 4 mA to power each LED for backlighting he used some 1978 vintage current limiting diodes designed to pass 2mA each regardless of voltage source, within limits of course.

Then the diode was known as a "valve," because it ... De Forest could control the flow of a second, more powerful current, through the tube. The strength of two currents was not necessarily ...

You are right that alternators are commonly replaced because their bearings, brushes, or slip rings wear out. Those are all ...

The flyback transformer is custom-wound with copper wire to achieve the necessary inductance for plasma generation. Its AC output is rectified to DC using a high-voltage microwave diode, as DC is ...
