ASVAB Electronics Practice Test 1

Question 1

Electrical power can be calculated with the following formula: P = I x V What does the letter I represent in this formula?

Accepted Answer

current

Answer

In the fundamental electrical power formula P = I x V, 'P' stands for power (measured in watts), 'V' stands for voltage (measured in volts), and 'I' represents electrical current. Current is the flow of electric charge and is typically measured in amperes (amps).

Question 2

What is the load in this basic circuit model?

Accepted Answer

C

Answer

In a basic circuit model (image not provided), the load is the component that consumes electrical energy and converts it into another form, such as light, heat, or motion. Assuming 'C' points to such a component in the unseen diagram, it represents the load, which is the part of the circuit doing the useful work.

Question 3

Three amps equals how many milliamps?

Accepted Answer

3,000

Answer

The prefix "milli-" denotes one-thousandth (1/1000) of a unit. Therefore, 1 amp is equal to 1,000 milliamps. To convert 3 amps to milliamps, you multiply 3 by 1,000. This calculation results in 3,000 milliamps.

Question 4

What type of electrical circuit is depicted above?

Accepted Answer

series-parallel circuit

Answer

A series-parallel circuit has some loads wired in series and some loads wired in parallel. The loads in this circuit are R1, R2, and R3. R1 is wired in series while R2 and R3 are wired in parallel.

Question 5

What device would you use to measure electrical resistance in a circuit.

Accepted Answer

ohmmeter

Answer

Electrical resistance is measured in ohms, and can be measured with an ohmmeter.
