Diodes are essential components found in electronic circuits. They allow current to flow in one direction while blocking it in the other. With time and usage, diodes can become defective, leading to ...

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 ...

This short article will deal with testing power MOSFETs using an ordinary digital multimeter. Anybody who have ever tried this must have marvelled at strange readings and short circuits found even on ...
