A shunt resistor is a very low value, high wattage resistor which is connected in parallel to a low range meter, so that it helps the meter to substantially increase […]
Meters and Testers
Microamp Meter Circuit
A microamp meter or microammeter is a device that allows the user to measure extremely small current levels, in microamps, which is normally not possible to measure using conventional multimeters. […]
Simple Crystal Tester Circuit
In this post I have explained how to build a simple crystal tester circuit using ordinary parts like transistors, resistors, diodes and capacitors. What is a Crystal A crystal can […]
2 Simple Milliohm Meter Circuits [Measure Low Resistances below 1 Ohm with these Circuits]
The low resistance measuring circuit I have explained below can be used for measuring all milliohm resistances below 1 ohm with extreme accuracy. The resistance to be measured can be […]
3-Digit LED Capacitance Meter Circuit
This project is yet another test equipment that can be extremely handy to any electronic hobbyist, and building this unit can be a lot of fun. A capacitance meter is […]
Match Transistor Pairs Quickly using this Circuit
In many critical circuit applications, like power amplifiers, inverters, etc it becomes necessary to use matched transistor pairs having identical hFE gain. Not doing this possibly creates unpredictable output results, […]
