Understanding PN Junction Diodes

What is a PN junction diode?

• A PN junction diode is a type of resistor that limits current flow.

• A PN junction diode is a semiconductor device that allows current to flow in one direction, formed by the junction of p-type and n-type materials.

• A PN junction diode is a device that can amplify signals in both directions.

• A PN junction diode is a type of capacitor used for energy storage.

What are the two types of semiconductor materials in a PN junction?

• P-type and N-type

• M-type and N-type

• P-type and S-type

• Q-type and R-type

What happens when a PN junction diode is forward-biased?

• The diode becomes an insulator.

• The diode generates heat.

• The diode conducts current.

• The diode blocks current.

What is the purpose of a diode in an electronic circuit?

• To allow current to flow in one direction and block it in the opposite direction.

• To amplify electrical signals.

• To store electrical energy for later use.

• To convert AC to DC voltage.

Can a PN junction diode conduct electricity in both directions?

• Yes, a PN junction diode can conduct electricity in both directions.

• A PN junction diode conducts electricity only in reverse bias.

• A PN junction diode can conduct electricity under high voltage conditions.

• No, a PN junction diode cannot conduct electricity in both directions.
