The forward voltage of rectifier diodes is low enough that a common ohmmeter can supply enough voltage to cause conduction.

Question

The forward voltage of rectifier diodes is low enough that a common ohmmeter can supply enough  voltage to cause conduction.

Quizplus · Accepted Answer

Ohmmeters are designed to measure resistance by applying a small voltage to the component being tested. This voltage is typically enough to forward bias rectifier diodes, causing them to conduct and allowing the ohmmeter to measure their forward voltage drop, which is usually low (around 0.6 to 0.7 volts for silicon diodes).
