Which of the following statements is correct for the identification of a diode using a multimeter?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → The multimeter displays current in one direction only
When a diode is tested with a multimeter:
→ In the forward bias direction, the multimeter shows a small current or voltage drop.
→ In the reverse bias direction, ideally no current flows.
∴ The multimeter displays current in one direction only
Correct option: The multimeter displays current in one direction only.
