By wrapping some wires around a toroidal core, you can make a 75 to 300 Ohm matching transformer. It will cost you no more than $5. It will cost you nothing if you can find a few copper wires and…
A multimeter is a versatile tool that can be used to measure a variety of electrical quantities. When working with electronic circuits and devices, measuring electric current in milliamps (mA) is common. But what does a 50-mA read mean on…
There are several ways to test a fuse without a multimeter including the light bulb technique, using an ohmmeter, visual inspection, etc. Using a fuse tester would be more accurate than using other instruments. A fuse is an electrical safety…
Measurement uncertainty is a quantifiable value that defines the range within which the actual measurement lies. This uncertainty may be impacted by a variety of elements when it comes to multimeters, including but not limited to intrinsic instrument error, operator…
Impedance and inductance have a specific and different impact during the flow of current in a particular circuit depending on passive elements present in that circuit. Impedance is a measurement of a circuit’s total opposition to electric current including both…
Both analog and digital oscilloscopes are used for the same work. But there are some extra features in a digital oscilloscope. The oscilloscope is an electronic measurement instrument. It is also known as an oscillograph, scope, CRO (cathode ray oscilloscope),…
Start with the FreeStyle Lite Meter off to do a complete reset. Holding down the “C” button while turning it on will bring up the configuration screen. When “SET” appears on the screen, press and hold the “M” button. Press…
The basic difference between UL 1558 and UL 891 is- UL 1558 is a switchgear construction standard while UL 891 is a switchboard construction standard. The construction of the switchboard UL 1558 has a fixed group mounting while the construction…
Film capacitors are used more than ceramic Capacitors. Film capacitors are suitable for a wide range of capacitance values whereas ceramic capacitors are suitable for a range of capacitance. Definition and Types of Capacitors Capacitors are electrical devices used to…
