PN Junction Quiz

What is a PN junction?

• A type of weather phenomenon

• A type of chemical reaction

• A type of computer network

• Boundary or interface between a P-type and N-type semiconductor material

What happens when a P-type semiconductor and an N-type semiconductor are joined together?

• It forms a parallel circuit

• It creates a superconductor

• It forms a PN junction

• It generates a magnetic field

What is the function of a PN junction in a diode?

• It allows the flow of current in both directions

• It amplifies the current in a diode

• It has no function in a diode

• It allows the flow of current in one direction while blocking it in the opposite direction.

How does a PN junction allow the flow of current?

• When it is forward biased

• When it is reverse biased

• When it is heated to a high temperature

• When it is disconnected from the circuit

What are the applications of PN junctions in everyday life?

• Toaster ovens, vacuum cleaners, and bicycles

• Television remotes, car tires, and kitchen utensils

• Diodes in electronic devices, solar cells, and LEDs

• Pencils, paper clips, and coffee mugs
