A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

A multimeter is a must-have tool for electrical projects. The hardest part about learning how to use a multimeter is learning to read the numerous symbols present on a multimeter. Once you can ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

[Norman] put together a rather impressive 22,500 uF capacitor bank. In addition to find things to torture with the strong magnetic field generated by a sudden discharge, he’d like to measure the ...
