Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

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 ...

Over the years, a wide variety of electrical meters has been developed to assist with monitoring and troubleshooting electrical systems. Let's take a look at some of the more common metering devices.
