When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

An ammeter is always connected in series with the component whose current you want to measure. This means it is placed ...

The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...

When working at high resistances, it becomes a significant factor. Caple capacitance increases the time to charge the cable, which can lead to additional settling time to make accurate measurements ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...
