ASVAB STUDY GUIDE (ELECTRONICS) EXAM QUESTIONS
Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -57 Questions and Answers
-Format: Multiple-choice / Flashcard
Question 1: Where can resistors be used?
Answer:
Circuit in series, in parallel, and in series-parallel
Question 2: Capacitive Reactance Formula
Answer:
X.C = 1/W^C
W = angular frequency C = capacitance
Question 3: Components of an Atom
Answer:
Protons, electrons, and neutrons
Question 4: Equivialent Resistance
Answer:
Sum of each resistance in the circuit
- Total voltage and total resistance in a series circuit is the sum of the voltage drops across each
component and the sum of the resistances in the circuit
Question 5: Farads
Answer:
Capacitance unit of measurement
Question 6: Electricity
Answer:
Energy produced from the motion of charged particles
Question 7: Circuit
Answer:
Heats conducting wires
Question 8: Volts
Answer:
Measures voltage (Newton x meter) per Coulomb
Question 9: Watts
Answer:
Measures power Joule per second
Question 10: Electromotive Force
Answer:
Voltage
- Difference in charge concentration results in voltage
Question 11: Fuses and Circuit Breakers
Answer:
Safety features that preserve the integrity of a circuit in the case of a power overload
Question 12: 2 protons
Answer:
Helium
Question 13: Resistance
Answer:
Inherent property of materials that hinders the passage of current through a conductor Measured in Ohms
Question 14: Diodes
Answer:
Electrical components that restrict the movement of current to only one direction and block the motion of current in the opposite direction
Question 15: Parallel Circuit
Answer:
Contains more than one path for the current to pass through
- Strength of the current will vary but voltage drop across each branch is the same
- If a branch is disconnected from the circuit the current will continue to pass through the remaining
branches (unlike series circuit)
Question 16: Cross Sectional Area in Relation to Resistance
Answer:
The larger the area the lesser resistance and the longer the conductor the greater the resistance
Question 17: What is used to bridge rectifiers to convert AC to DC
Answer:
Diodes
Question 18: Voltage
Answer:
Electric potential difference between two charged points in an electric field
- Only meaningful when considering one point in relation to another
Measured in Volts
Question 19: Series Circuit
Answer:
All components of the circuit are connected one after the other
- Only one path for current to take
Question 20: Amperes
Answer:
Measure current Coulomb per second
Question 21: Most Common Semiconductors
Answer:
Silicon and germanium
Question 22: Electron Flow Theory
Answer:
Behavior of electrons when moving through a conductor
- Negatively charged electrons flow from the negative terminal (ANODE) to the positive terminal
(CATHODE)
- In response to the attractive and repulsive forces between the charged particles
Question 23: Grounding
Answer:
Method of neutralizing a charged object by connecting it to a much larger source of charge (most commonly the Earth)
Question 24: Why are metals good conductors?
Answer:
Electrons flow easily through them without much resistance
Question 25: Alternators produce...
Answer:
AC
Question 26: Ohms
Answer:
Measure resistance Volt per amp
