Question 2

Question 2

Revolt · Accepted Answer

[Dropdown 1] transistor; transistor

Question 3

Which is a dopant for a p-type semiconductor?

Revolt · Accepted Answer

indium

Question 4

Which statement is true for both types of transistors?

Revolt · Accepted Answer

The base is between the collector and the emitter.

Question 5

Which lists the layers in a PNP transistor from the least negative to the most negative?

Revolt · Accepted Answer

emitter, base, collector

Question 6

Which best describes the two main functions of transistors in circuits?

Revolt · Accepted Answer

switching and amplifying

Question 7

Which best describes an example of a p-type semiconductor?

Revolt · Accepted Answer

It uses boron so that electrical conduction is due to the movement of a positive charge.

Question 8

Angela sees a puzzle that uses a board with 20 holes drilled into it. There are 18 pegs in the holes, and the goal of the puzzle is to move the pegs by hopping them into the open holes until both holes are at one end of the board. How could Angela use the puzzle to model semiconductors?

Revolt · Accepted Answer

as an n-type semiconductor with the pegs representing electrons and the holes representing positive charges

Question 9

In which type of transistor does current flow from the base to the emitter?

Revolt · Accepted Answer

an NPN transistor, which has a p-type base

Question 10

Which is a dopant for a semiconductor that conducts electricity due to the movement of positive charges?

Revolt · Accepted Answer

thallium
