79. An ohmmeter used to test for front-to-back resistance of a PN junction diode should produce roughly what ratio?
A 100:1 ratio is the expected forward-to-reverse resistance ratio when testing a PN junction diode with an ohmmeter. This value is practical and within the resolution of a standard ohmmeter, indicating proper rectification without requiring extreme precision.
