NCATT AET TEST STUDY GUIDE
2025 QUESTIONS AND ANSWERS
What part of an atom is associated with the flow of electricity? -
....ANSWER ...-Electrons
What in electrons in a conductor determines whether its flow is poor or good? -
....ANSWER ...-Whether or not there contain free electrons in the orbit of
atoms
Define Static Electricity. - ....ANSWER ...-a difference of electrical charge
between two non-conductive surfaces
What term is used to express the flow of electricity? - ....ANSWER ...-
Amperes is the amount of current flowing in a circuit
What is a coulomb? - ....ANSWER ...-a basic unit of electrical quantity equal
to 6.28 x 10^18 or 6.28 billion billion electrons
What is the basic unit of electrical pressure? What other names could it go by? -
....ANSWER ...-Electron Motive Force (EMF) or Volts

, If voltage and resistance are known, describe how total current can be determined.
Show the equation. - ....ANSWER ...-To determine the current in a circuit,
the voltage is divided by the resistance. I=V/R
What device other than an actual battery can be used to store energy? -
....ANSWER ...-A capacitor
Describe the left hand rule as it pertains to electrical generation. -
....ANSWER ...-This describes the flow of current in a conductor when
passed through magnetic lines of flux. Thumb represents motion of conductor,
index finger represents line of flux of magnetic field, middle finger is resultant
current flow.
What trait would allow magnetic lines of flux to flow easily? -
....ANSWER ...-the permeability of the material that the lines of flux flow
through
Describe the name of a common electrical point that allows circuits to have a
return path to power. - ....ANSWER ...-earth or chassis ground
What is the result of passing too much current (amps) in a small gauge wire? -
....ANSWER ...-a larger amount of resistance will slow the rate of current
flow
