ASVAB Electronics Exam Question With
Correct Answers
Electricity - answer✔General term for the variety of phenomena resulting from the presence and flow of
electric current
Volts
Amperes (amps)
Ohms - answer✔3 ways Electricity is measured
Volts - answer✔Measure the difference of potential between 2 points
Amperes (amps) - answer✔Measure the number of electrons that move past a specific point in 1 second
(i.e. electrical currents)
Ohms - answer✔Measure resistance, including anything that could limit the flow of electrons
Current - answer✔Electrical ___ occurs when electrons move from one place to another.
Conductors
(e.g. copper, silver, water) - answer✔A substance, body, or device that conducts electricity; allows the
electrons to move freely.
Insulators
(e.g. rubber, wood) - answer✔A material of such low conductivity that does not easily allow the flow of
electrical current to pass through it; discourages electrical current
Watt - answer✔This measures power, the rate at which electrical energy is consumed or transformed
into another type of energy, such as light or heat
Power - answer✔The rate at which electrical energy is consumed or transformed into another type of
energy, such as light or heat
Watt-hour - answer✔This is the amount of energy used in 1 hour at a rate of 1 watt.
Kilowatt-hour - answer✔The amount of energy used in 1 hour at a rate of 1,000 watts(i.e.1-kilowatt)
Wattage x Time (expressed in hours) - answer✔To find watt-hours multiply ___ by ___.
10 kilowatt-hours - answer✔How many kilowatt-hours is enough energy to run a 10,000-watt speaker
system for 1 hour?
2 hours - answer✔10 kilowatt-hours is enough energy to run a 5,000-watt air conditioner for how long?
10 hours - answer✔10 kilowatt-hours is enough energy to run a 1,000-watt waffle iron for how long?
Circuit - answer✔The path of an electrical current
Open - answer✔When there is literally an open space in the circuit that prohibits current from flowing
Short - answer✔When the open space of a circuit has been closed to allow current to flow
Voltage - answer✔The difference of the pressure between 2 points in a circuit
(sometimes called voltage drop or difference of potential)
True - answer✔True or False
To see what the voltage is anywhere in a circuit, you have to compare the voltage at that point to
ground
Ground
(e.g. base of a lamp, chassis of a car) - answer✔Any part of a circuit (or other object that has electricity
running through it) that measures 0 volts
Voltmeter or multimeter - answer✔Measures voltage in a circuit
Voltmeter - answer✔An instrument used for measuring electrical potential difference between two
points in an electric circuit (i.e. voltage)
A voltmeter has 2 leads. To measure voltage, you place one lead somewhere in the circuit and one lead
at another location in the circuit. The voltmeter tells you what the voltage is between those 2 points. -
answer✔How to use a voltmeter:
Cell - answer✔A storage compartment for electricity in a battery that has a specific voltage.
True - answer✔True or False
You can figure out the number of cells a battery has by dividing the voltage of the battery by the volts.
Electrical current - answer✔The flow (rate of flow) of electrons in a conductor
