We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

The unit can also be used for basic diode tests on bipolar transistors, although the test current may be too high for the base connection of some devices. The circuit was designed to be simple and ...

Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor‘s BZX55C15RL, which has a working voltage of 13.8 to 15.6V. The voltage in Figure 4was measured ...

For testing diodes, the waveform generator is configured ... it should behave like an open circuit. For testing cables, the waveform generator is configured to output a 100-Hz, 0-V to 1-V square ...

Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

In the meantime, check out his previous experiments with copper oxide diodes. And if you want to see a steering circuit made with conventional diodes then we’ve previously talked about [Fran ...
