ELECTRICAL CRAFT HELPER PRACTICE FINAL TEST 2026
QUESTIONS WITH CORRECT ANSWERS GRADED A+
● 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.
● What is the atom?. Answer: It is the smallest particle that makes up that type of material
called an ELEMENT.
● What retains its characteristics when subdivided into atoms?. Answer: Elements
● What is the core of the atom called. Answer: Nucleus
● Where is most of the mass of the atom concentrated in?. Answer: Nucleus
