Subelement G6 question review

All 23 official questions with the exact winning phrase marked.

G6A01G6A

What is the minimum allowable discharge voltage for maximum life of a standard 12-volt lead-acid battery?

C10.5 volts

Why this answer

The key fact is 10.5 volts. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.

E = I × R

G6A02G6A

What is an advantage of batteries with low internal resistance?

BHigh discharge current

Why this answer

The key fact is High discharge current. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.

E = I × R

G6A03G6A

What is the approximate forward threshold voltage of a germanium diode?

B0.3 volts

Why this answer

The required value is 0.3 volts. Keep the units with the number so a nearby distractor cannot pull you away from the result.

Memory hook: A diode normally lets current favor one direction.

E = I × R

G6A04G6A

Which of the following is characteristic of an electrolytic capacitor?

CHigh capacitance for a given volume

G6A05G6A

What is the approximate forward threshold voltage of a silicon junction diode?

C0.7 volts

Why this answer

The required value is 0.7 volts. Keep the units with the number so a nearby distractor cannot pull you away from the result.

Memory hook: A diode normally lets current favor one direction.

E = I × R

G6A06G6A

Why should wire-wound resistors not be used in RF circuits?

BThe resistor’s inductance could make circuit performance unpredictable

G6A07G6A

What are the operating points for a bipolar transistor used as a switch?

ASaturation and cutoff

G6A08G6A

Which of the following is characteristic of low voltage ceramic capacitors?

DComparatively low cost

Why this answer

The key fact is Comparatively low cost. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.

Memory hook: Capacitors store energy in an electric field.

E = I × R

G6A09G6A

Which of the following describes MOSFET construction?

BThe gate is separated from the channel by a thin insulating layer

G6A10G6A

Which element of a vacuum tube regulates the flow of electrons between cathode and plate?

AControl grid

G6A11G6A

What happens when an inductor is operated above its self-resonant frequency?

CIt becomes capacitive

G6A12G6A

What is the primary purpose of a screen grid in a vacuum tube?

ATo reduce grid-to-plate capacitance

G6B01G6B

What determines the performance of a ferrite core at different frequencies?

CThe composition, or “mix,” of materials used

G6B02G6B

What is meant by the term MMIC?

BMonolithic Microwave Integrated Circuit

G6B03G6B

Which of the following is an advantage of CMOS integrated circuits compared to TTL integrated circuits?

ALow power consumption

G6B04G6B

What is a typical upper frequency limit for low SWR operation of 50-ohm BNC connectors?

C4 GHz

Why this answer

The key fact is 4 GHz. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.

Memory hook: Lower SWR means the feed line and load are better matched.

E = I × R

G6B05G6B

What is an advantage of using a ferrite core toroidal inductor?

DAll these choices are correct

G6B06G6B

What kind of device is an integrated circuit operational amplifier?

DAnalog

G6B07G6B

Which of the following describes a type N connector?

AA moisture-resistant RF connector useful to 10 GHz

G6B08G6B

How is an LED biased when emitting light?

DForward biased

G6B10G6B

How does a ferrite bead or core reduce common-mode RF current on the shield of a coaxial cable?

ABy creating an impedance in the current’s path

Why this answer

Use this action or method: By creating an impedance in the current’s path. It is the choice that directly completes the job described in the question.

E = I × R

G6B11G6B

What is an SMA connector?

BA small threaded connector suitable for signals up to several GHz

G6B12G6B

Which of these connector types is commonly used for low frequency or dc signal connections to a transceiver?
