Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Find a downloadable version of this story in pdf format at the end of the story. Silicon Schottky diodes are used in power applications because of their low forward voltage drop, which allows lower ...
