Question 1

The function of the voltage regulator is to control the output voltage by controlling the amount of&#160; excitation current supplied to the field or rotor.

Accepted Answer

The voltage regulator controls the output voltage of a generator or alternator by adjusting the amount of excitation current supplied to the rotor or field windings, thereby stabilizing the output voltage despite changes in load or input voltage.

Question 2

____ is used more often in the production of transistors because of its ability to withstand heat.&#10;A) Germanium&#10;B) Silicon&#10;C) Arsenic&#10;D) Iron

Accepted Answer

Silicon is preferred in the production of transistors due to its superior ability to withstand high temperatures, making it more reliable and efficient for electronic devices.

Question 3

Electronic technicians and engineers coined the term &#34;____&#34; to describe when a piece of equipment&#160; suddenly stopped operating.&#10;A) blue plague&#10;B) black plague&#10;C) purple plague&#10;D) red plague

Accepted Answer

The term "purple plague" refers to a specific failure mode in electronics, particularly in connections or solder joints, where the material deteriorates, leading to sudden failure of the equipment.

Question 4

A transistor is the same thing as a variable resistor.

Accepted Answer

A transistor is a semiconductor device used to amplify or switch electronic signals, whereas a variable resistor (potentiometer) is used to adjust the level of resistance in a circuit.

Question 5

The transistor is a semiconductor device made by joining together three layers of P- or N-type&#160; material.

Accepted Answer

A transistor is indeed a semiconductor device that consists of three layers of P-type or N-type material, forming either a PNP or NPN junction, which is used to amplify or switch electronic signals.

Question 6

____ is caused by a semiconductor's characteristic of decreasing resistance with an increase of&#160; temperature.&#10;A) Thermal runaway&#10;B) Thermal inversion&#10;C) Thermal conversion&#10;D) Thermal cascade

Accepted Answer

Thermal runaway occurs in semiconductors when an increase in temperature leads to a decrease in resistance, which in turn allows more current to flow, further increasing temperature. This feedback loop can lead to device failure if not properly managed.

Question 7

The ohmmeter test is considered to be about 75 percent accurate.

Accepted Answer

The accuracy of an ohmmeter test can vary widely depending on the specific meter used, its calibration, the conditions under which the test is performed, and the specific application. There is no standard accuracy rate such as 75 percent that applies universally to all ohmmeter tests.

Question 8

The ____ generally determines the amount of power the transistor is designed to control.&#10;A) design of the case&#10;B) material of the case&#10;C) size of the case&#10;D) type of case

Accepted Answer

The answer of The ____ generally determines the amount of...

Question 9

The transistor follows all the rules of ____'s Law.&#10;A) Ohm&#10;B) Coulomb&#10;C) Newton&#10;D) Watt

Accepted Answer

The transistor, being an electronic component used for amplification and switching, follows Ohm's Law in its operation. Ohm's Law relates the voltage across a conductor to the current through it, with the resistance being the proportionality constant.

Question 10

A silicon device requires less voltage to operate than a germanium one.

Accepted Answer

Silicon devices typically require a higher voltage to operate than germanium devices because silicon has a wider band gap than germanium.
