AET NCATT Questions with CORRECT Answers
Question:
What part of an atom is associated with the flow of electricity?
Answer:
Electrons
Question:
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
Question:
Define Static Electricity.
Answer:
a difference of electrical charge between two non-conductive surfaces
Question:
What term is used to express the flow of electricity?
Answer:
Amperes is the amount of current flowing in a circuit
Question:
What is a coulomb?
Answer:
a basic unit of electrical quantity equal to 6.28 x 10^18 or 6.28 billion billion electrons
Question:
What is the basic unit of electrical pressure? What other names could it go by?
Answer:
Electron Motive Force (EMF) or Volts
, Question:
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
Question:
What device other than an actual battery can be used to store energy?
Answer:
A capacitor
Question:
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.
Question:
What trait would allow magnetic lines of flux to flow easily?
Answer:
the permeability of the material that the lines of flux flow through
Question:
Describe the name of a common electrical point that allows circuits to have a return
path to power.
Answer:
earth or chassis ground
Question:
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
