ELECTRICAL CRAFT HELPER
TEST 2024
What is Matter? - ANSWER Matter is anything that has mass and
occupies space. It contains millions of invisible particles called
molecules
What is Matter made of? - ANSWER Matter is made of molecules and
atoms
What is a Molecule? - ANSWER A molecule is the smallest particle
into which matter can be divided without changing its identity and
still be called by the same name. All molecules are composed of
atoms.
What is an Electrical Current? - ANSWER It is Electricity in motion
and represents the transfer of energy from one place to another and
the flow of electrons in a conductor. Electricity is also capable of
converting energy from one form to another.
Name six sources of power from raw energy - ANSWER Coal, oil,
natural gas, uranium, wood & wind.
Name the three specialized technical steps that provide electricity -
ANSWER Generation, Transmission & Distribution
How does a generator plant produced electricity - ANSWER Its
produce by turning a shaft, on which is mounted a powerful
electromagnet. The shaft turns inside a cylindrical iron shell called a
stator. The rotating electromagnetic field, acting on wire coils in the
stator, produces electricity.
What is a Volt? - ANSWER It is the unit of electrical pressure or
electromotive force or potential difference. Electricity flowing along
a wire may be compared to water flowing through a pipe.
