Proper safety procedures are critical when testing high-voltage systems. As the following examples prove, mistakes happen. However, when the safety of you and your coworkers is at stake, neglecting ...

Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...

Voltage tester, tick-tracer, glow-tip, non-contact voltage tester... whatever. Same thing. I call it a voltage sniffer, but the technical name for this device is a capacitive voltage sensor. That's a ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

Moderate drop: Indicates partial aging — monitor closely and retest soon. Severe drop or collapse: The battery is nearing end-of-life or has an internal fault. Tracking battery load test results helps ...

If a poll was taken to determine what aspect of the hot rod hobby enthusiasts dislike the most, there’s a high likelihood that “diagnosing electrical issues/gremlins” would be the popular answer. An ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...
