multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in most cases‚ although using the device with the current on can sometimes

Electrical circuit is a path which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an
