🔍 Key Concepts

• Forward and reverse resistance of diodes and transistor junctions • How a good fuse and a good bypass capacitor should read on an ohmmeter • What ohmmeter readings (short, open, or normal junction drop) usually indicate a faulty semiconductor junction

💭 Think About

• For each choice, ask: does this describe what a healthy component should read, or what a failed component would read? • Think about how a diode and transistor junctions behave like one-way valves for current. What should the meter show in the forward direction vs. reverse direction? • Consider what an in-line fuse and bypass capacitor are supposed to do in a DC circuit. Would you expect to see continuity (low ohms) or open (very high/infinite ohms)?

✅ Before You Answer

• For the diode choice, verify that a good diode conducts one way and blocks the other — what ohmmeter pattern does that give? • For the fuse choice, recall that a good fuse must pass DC current — should it read near zero or infinite ohms? • For the transistor choice, compare the expected readings between base-emitter and base-collector junctions in both directions; ask if low resistance both ways is normal or suggests a shorted junction.

Question 1 of 20

What ohmmeter reading may indicate a faulty component in a VHF receiver?

Low resistance across a diode in one direction, high resistance when test leads are reversed.

Zero ohms across an in-line fuse in a DC power circuit.

Infinite ohms across a ceramic bypass capacitor in a transistor amplifier circuit.

A transistor indicates low resistance between emitter and base when test leads are reversed across them.
