ELECTRICAL CRAFT HELPER EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+
Shells
Any of the space occupied by the orbit of a group of electrons
of approximately equal surrounding the nucleus of an atom
Static electric charge
Electric charge at rest Caused by friction of materials, where a
a surplus of electrons exists and may be discharged.
Electron flow
The condition where the free electrons are cause to move in
the same direction along or through a conductor
Current
Occurs when a stream of electrons are caused to move
through a conductor
Ampere
, Rate of electron flow (current flow). When one "coulomb" of
electrons pass a given point in one second.
Primary cell
A cell which is composed of certain materials which are use
during the process of delivering electric current
Electrode
The dissimilar metals which are place in an electrolyte to
form a cell.
Electrolyte
The liquid solution (sometimes a paste) in which the
electrodes are place.
Secondary cell
A cell which is rechargeable. Use materials which change in
composition during delivery of current, but may restore to
original condition upon recharge
Plates
That electrodes of a cell shaped as plates to expose a surface
as possible to the electrolytes.
Storage battery
Several secondary cell connected together for either a great
voltage or current output
Magnetism
