NCATT AET EXAMINATION TEST 2026
COMPLETE PRACTICE QUESTIONS AND
UPDATED SOLUTIONS
⩥ 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.
⩥ How is voltage distributed in a parallel circuit? Answer: voltage is
equal to the branches while current will be cumulative of each branch
⩥ Describe the rule for current and magnetism for the left hand rule for
generators Answer: thumb = direction of motion conductor, index finger
