Question 1

If no current flows through the base of the transistor, the transistor acts like a closed switch.

Accepted Answer

If no current flows through the base of a transistor (in the case of a bipolar junction transistor), it acts like an open switch, not allowing current to flow from collector to emitter.

Question 2

One of the most common applications of the transistor in industry is that of a ____.&#10;A) resistor&#10;B) CPU&#10;C) zener diode&#10;D) switch

Accepted Answer

Transistors are widely used as switches in electronic circuits. They can rapidly switch between on and off states, controlling current flow in a circuit without mechanical movement.

Question 3

When the TO3 transistor is held with the leads facing you and down, the ____________________ is the left lead.

Accepted Answer

emitter

Question 4

An ohmmeter can be used to test a transistor, which will appear to the ohmmeter to be two joined ____.&#10;A) diodes&#10;B) resistors&#10;C) capacitors&#10;D) AND gates

Accepted Answer

An ohmmeter can be used to test a transistor, which will appear as two joined diodes because a transistor is essentially made up of two PN junctions, similar to the structure of diodes.

Question 5

Transistors are made by connecting three pieces of semiconductor material.

Accepted Answer

Transistors are made by connecting three pieces of semiconductor material, typically silicon, in a configuration known as PNP or NPN, where P stands for positive (or p-type semiconductor) and N stands for negative (or n-type semiconductor).
