NCATT AET EXAM NEWEST 2026/2027 QUESTIONS
and CORRECT DETAILED ANSWERS ALREADY
GRADED A+
Ohms law states - CORRECT ANSWER-the amount of current flowing in a
circuit is directly proportional to the circuit voltage and inversely proportional to
the circuit resistance
Ohm's Law - CORRECT ANSWER-I= V/R, Current is equal to Voltage divided by
resistance
Watt - CORRECT ANSWER-a basic unit of electrical power that is the product of
voltage multiplied by current
One Watt equals - CORRECT ANSWER-1/746 horsepower
One watt is produced when - CORRECT ANSWER-a circut that has one amp of
current flowing under a pressure of one volt
First rule of series circuits - CORRECT ANSWER-there is only one path for
current to flow therefore current equal throughout the circuit
,Direct current is defined as - CORRECT ANSWER-the flow of electrons in one
direction throughout a circuit with constant voltage and current
Faraday's Law - CORRECT ANSWER-current will flow in a circuit provided there
is electrical difference in potential and there is a path for it to flow
Loads slow current by - CORRECT ANSWER-applying resistance
Current flows from - CORRECT ANSWER-negative to positive
Atoms - CORRECT ANSWER-represent the smallest elements that exist in
nature
Atoms are made up of - CORRECT ANSWER-protons, neutrons and electrons
Nucleaus - CORRECT ANSWER-center of the atom
Electrons travel - CORRECT ANSWER-at the speed of light
Protons - CORRECT ANSWER-positively charged subatomic particles
,Protons contain - CORRECT ANSWER-a positive electrical potential
Protons positive charge - CORRECT ANSWER-affect the orbits of the electrons
Neutrons are - CORRECT ANSWER-neutral subatomic particles
Neutrons are not involved - CORRECT ANSWER-in the conduction of electricity
Electron's charge - CORRECT ANSWER-is negative
The speed of rotation combined with electrical potential - CORRECT ANSWER-
keeps the electrons in their orbits
The attraction of opposite charges - CORRECT ANSWER-holds the electron in
its orbit
Conductors - CORRECT ANSWER-easily permit the movement of electrons
from an electrical source to a load and back to the electrical source with a
minimum of resistance
, First two inner orbits - CORRECT ANSWER-make up the atomic number for the
element
During conductance an extra valence electron - CORRECT ANSWER-flows into
the next atoms valance orbit
Good conductors - CORRECT ANSWER-Only those elements that dont hang on
to their valence electrons
Good Insulators - CORRECT ANSWER-Elements that don't give up valance
electrons no matter what force is applied
lators - CORRECT ANSWER-a material or device used to prevent the passage of
heat, electricity or sound from one medium to another
Examples of insulators - CORRECT ANSWER-Glass, Mica, Silica
Air - CORRECT ANSWER-can be a good insulator but will spark when enough
electrical force is applied
