The purpose of a multimeter is to enable you to test electrical circuits and record resistance, voltage and current measurements for future reference. Recording circuit measurements during alarm ...

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 ...

How do you know if a resistor is correctly restricting the flow of electricity? Using a multimeter is an obvious answer. However, there is more to it than meets the eye. This article will explain what ...
