GUIDE PRACTICE QUESTIONS
AND CORRECT ANSWERS
LATEST UPDATE
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
, Page |2
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
, Page |3
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
, Page |4
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
