Accurately measure and troubleshoot electrical voltage, current, and resistance with this useful addition to your toolbox.

Basic functionality includes measurement of potential in volts, resistance in ohms, and current in amps. Multimeters are used to find electronic and electrical problems. Advanced units come with more ...

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 ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

It’s remarkable how tiny electronics have become. Heaven knows what an old-timer whose experience started with tubes must think, to go from solder tags to SMD in a lifetime is some journey. Even the ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...
