🔍 Key Concepts

• How a diode is supposed to conduct in forward bias versus reverse bias • What an ohmmeter reading near zero, mid-scale, or infinity typically means for continuity • The difference in readings for a good diode, a shorted diode, and an open diode

💭 Think About

• Think about what you expect to see on an ohmmeter when a diode is forward biased and working properly. Should you see low resistance, high resistance, or infinity? • Now think about reverse bias on a healthy diode. Should it block current completely, or show some conduction? What would the ohmmeter show? • Compare that expected behavior to a situation where both directions show almost infinite resistance. What physical condition inside the diode would cause no current to flow in either direction?

✅ Before You Answer

• Be clear on what infinity on an ohmmeter means: effectively no current / open circuit • Recall that a good diode will show low resistance one way and very high resistance the other way • Eliminate any choice that would imply very low resistance in at least one direction, since the question states both readings are almost infinity
