hard 5 Questions
Question 1 of 5

What type of semiconductor material has holes as majority carriers?

P-type materials are doped to have an excess of holes, which act as the majority charge carriers.
Question 2 of 5

What is the primary function of a diode?

Diodes are commonly used to convert AC to DC by allowing current to flow in only one direction.
Question 3 of 5

Which terminal of a diode is typically denoted by 'K'?

The cathode is the negative terminal and is usually marked with the letter 'K'.
Question 4 of 5

What is formed when P-type and N-type materials are joined?

The junction where P-type and N-type materials meet is called the PN junction.
Question 5 of 5

What is the depletion region?

The depletion region is formed by the recombination of electrons and holes, leaving a region with very few charge carriers.
