Which of the following statements is correct for the identification of a diode using a multimeter?
- A The multimeter shows an initial deflection which falls to zero
- B The multimeter displays current in one direction only
- C The multimeter displays current in both directions
- D Multimeter can not identify a diode
Answer & Solution
Correct Answer
(B) The multimeter displays current in one direction only
Step-by-step Solution
Detailed explanation
A diode is a unidirectional device. When tested with a multimeter, it allows current to flow in forward bias (low resistance) but blocks it in reverse bias (high resistance). This one-way conduction distinguishes it from other components like resistors or capacitors.
