NCATT AET TEST STUDY GUIDE (NCATT ARICRAFT
ELECTRONIC TECHNICIANS STUDY SET) 2025
QUESTIONS & ANSWERS SOLVED 100% CORRECT.
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
Describe the relationship of voltage, current, and resistance described in Ohms
law. Answer - the electrical pressure of 1 volt is equal to the flow of 1 amp of
current times the resistance of 1 ohm
How much work can be achieved with one watt of energy? Answer - 1 watt =
1/746th of horsepower
Describe what current does in a series circuit. Answer - The flow of current is
common across all resistance loads around the circuit.
