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

SET) 2025 QUESTIONS & ANSWERS SOLVED 100% CORRECT.
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 = the direction of magnetic field, middle finger = the
resultant of current flow
What large difference of electrical potential has no useful purpose in aviation? - (ANSWER)Static
electricity
What is the property called when lines of magnetic flux travel freely through a material? - (ANSWER)only
materials with HIGH PERMEABILITY will pass lines of magnetic flux
What is basic unit of measure for capacitor? - (ANSWER)Farads
