3. What to expect on the ASVAB Electronics Information ? 


Candidates must become familiar with three key topics that run throughout the ASVAB electronics information examination in order to perform well on the exam. Keep in mind that candidates are expected to have a fundamental comprehension of equations that affect the principles of electricity when taking the electronics information exam.


3.1. Measurement Electricity 


Candidates must comprehend the principles of electricity’s physics. This necessitates a thorough knowledge of volts, amperes, Ohms, and coulombs. Additionally, you should be aware of what watts and kilowatt-hours are used for measuring in terms of current flow.


3.2. Circuits 

electronics information asvab practice test circuits
Circuits are a common topic in ASVAB test questions.

Circuits are a common topic in ASVAB test questions. The symbols of electrical devices, alternating and direct current, capacitors, inductors, transistors, cables, fuses, transducers, different kinds of switches, diodes, amplifiers, and antennae are among the subjects covered.


3.3. Electrical Principles


The fundamentals that underpin electronics, such as the many forms of resistance, Ohm’s law, frequency, impedance, and the direction of electrical flow, should still be understood even though the electronics information test is not factored towards the AFQT score.


4Test Taking Tips for the ASVAB Electronics Information Subtest


Candidates must prepare for the ASVAB electronics information exam in the weeks and months prior to the examination by answering as many ASVAB practice questions as they can.

4.1. Interpret electrical systems


Candidates should at the very least be well-versed in electrical circuits and their principles of operation. Understanding electrical symbols is essential for this. All electrical symbols must be committed to memory, preferably with the aid of flashcards.


4.2. Learn more Conductors and insulators


Make a list of the materials that are insulators and conductors are most frequently found. These are compounds that either conduct electrical current widely or resist it widely. Despite not making up a large portion of the electronics knowledge exam, they are assessed, and the results can be straightforward!


4.3. Know units and equations


Candidates should also make flashcards that cover scientific units and equations like Ohm’s law. You must be able to specify the purposes for using these equations as well as the units that are utilized for each factor. The best way to study for units and equations is with flashcards.


4.4. Practice ASVAB test questions by Estudyme


One of the exams that concentrates on facts is the one on electronics information. In the weeks prior to the test, try to complete as many ASVAB Electronics Information Practice Tests as you can. Explained solutions can also fill in any knowledge gaps you may have, transforming any deficiencies you may have into strengths.


5. ASVAB Electronics Information Sample Questions with Answers


Here are 10 sample Electronics Information questions with their detailed explanations. Don’t forget to read the best ASVAB Electronics Information Study Guide first. 

ASVAB EI Practice Test
10 sample Electronics Information questions

Question 1: Which of the following statements is INCORRECT regarding Ohm’s Law?

A. Current is inversely proportional to the resistance.

B. Voltage is directly proportional to both current and resistance.

C. Voltage is directly proportional to the current.

D. Voltage is inversely proportional to the resistance.

Correct Answer: D


Ohm’s law states that V = IR. According to the law, voltage is directly proportional to both current and resistance while current is inversely proportional to the resistance.


Question 2: Which of the following is the most conductive element?

A. Aluminum

B. Copper

C. Gold

D. Silver

Correct Answer: D


The most conductive material is Silver followed by Copper and Gold.


Question 3: If a transformer has a primary winding with 200 turns and a secondary winding with 40 turns, what is the transformation ratio?

A. 1:5

B. 10:5

C. 5:1

D. 5:5

Correct Answer: C


The transformation ratio for a transformer compares the number of turns in the primary winding to the number of turns in the secondary winding. In this case, that ratio is 200:40 which reduces to 5:1.


Question 4: Which type of capacitor is best suited for high frequency applications?

A. Electrolytic

B. Mica

C. Mylar

D. Tantalum

Correct Answer: B


Mica has a very special use in electronics. Mica capacitors are used for high frequency applications.


Question 5: An amplifier is most similar in function to which of the following:

A. A capacitor

B. A step-up transformer

C. An inductor

D. An inverter

Correct Answer: B


An amplifier is a device that takes a small input signal and creates a larger output signal. This makes it most similar to a step-up transformer which takes a smaller input voltage and creates a larger output voltage.


Question 6: What is the voltage of most household electrical systems?

A. 110V

B. 220V

C. 60Hz

D. 60MHz

Correct Answer: A


Most households use electricity with a voltage of 110V.


Question 7: Capacitors connected in series produce _____ capacitance compared to capacitors connected in parallel.

A. Double

B. Less

C. More

D. The same

Correct Answer: B


Capacitors connected in series produce less capacitance than capacitors connected in parallel.


Question 8: Winding wire into a coil will have what effect on the magnetic field in the wire?

A. Make it stronger

B. Make it weaker

C. No change

D. Removes the magnetic field

Correct Answer: A


Bringing the wire closer together increases the strength of the magnetic field. An electromagnetic coil brings the wires very close together in a loop around a core.


Question 9: Electrical “pressure” is also known as:

A. Charge

B. Conductivity

C. Ohms

D. Voltage

Correct Answer: D


Voltage is a measurement of electrical pressure and will sometimes be described as something similar to the pressure in a water line.


Question 10: How many volts does it take to send 99 Amps of current through 99,000 Ohms of resistance?

A. 0.009801 Volts

B. 9.801 Megavolts

C. 98.01 Volts

D. 980.1 Megavolts

Correct Answer: B


99 Amperes * 99,000 Ohms = 9,801,000 Volts
