🔍 Key Concepts

• PN junction diode characteristics in forward bias vs reverse bias • Typical front-to-back (forward-to-reverse) resistance ratio for a healthy small-signal diode • How an ohmmeter applies a small voltage and measures current to infer resistance

💭 Think About

• First, think about how much easier current flows in the forward direction of a diode compared to the reverse direction—does it differ by tens, hundreds, or thousands of times? • Consider what would be a realistic ratio that allows an ohmmeter to clearly show a difference between forward and reverse resistance without requiring extremely sensitive instrumentation. • Ask yourself: for a standard silicon diode, is the reverse resistance just slightly higher, moderately higher, or much, much higher than the forward resistance?

✅ Before You Answer

• Make sure you understand that forward resistance is low and reverse resistance is high for a good diode. • Consider which ratio would give a clear distinction on a typical analog or digital ohmmeter used in basic troubleshooting. • Eliminate any option that seems too small to show a clear diode effect or unrealistically large for a basic meter test.
