CFESA ELECTRICAL FINAL EXAM
REVIEW 2026/2027
can you define and test a ground? - ANSWER-a ground is a point in the circuit that is
connected to the earth. you can use a multimeter-If the resistance is too high, it may
indicate that the ground connection is not providing adequate protection
electrical safety rules - ANSWER-1.Always use a circuit tester or voltage detector to
check that a circuit is de-energized before working on it.
electrical safety rule - ANSWER-Never touch electrical wiring or equipment with wet
hands or while standing on a wet surface.
electrical safety rule - ANSWER-Do not operate electrical equipment that is damaged,
frayed, or otherwise in poor condition.
electrical safety rule - ANSWER-Use the correct fuse or circuit breaker for the circuit
you are working on.
electrical safety rule - ANSWER-Never remove or bypass the grounding prong on a
plug.
Electrical Safety - ANSWER-Do not use extension cords or multiple outlet adapters that
are not rated for the equipment you are using.
electrical safety - ANSWER-Do not overload circuits by plugging in too many devices or
using high-powered equipment.
electrical safety - ANSWER-Do not use electrical equipment in wet or damp conditions
unless it is specifically designed for that purpose.
electrical safety - ANSWER-Use properly rated and properly installed surge protectors
for sensitive electronic equipment.
electrical safety - ANSWER-Always follow the manufacturer's instructions for using
electrical equipment.
purpose of lockout tag out - ANSWER-to prevent unexpected energization or startup of
machinery or equipment while it is being serviced or repaired.
state the two types of electrical current - ANSWER-AC and DC
, how to use a circuit tester - ANSWER-To test a circuit, first locate the circuit breaker or
fuse that controls the circuit you want to test. Then, using the circuit tester, touch the red
probe to the live wire and the black probe to the neutral or ground wire.
what is a power source - ANSWER-The power source is the source of electrical energy
for the circuit. It can be a battery, a generator, or a power outlet. The power source
provides the electrical current that flows through the circuit.
what is a conductor - ANSWER-The conductor is a material that allows electricity to flow
through it, such as a wire. The conductor carries the electrical current from the power
source to the load.
what is a load - ANSWER-The load is the device or appliance that is being powered by
the circuit. It can be a light bulb, a motor, or any other device that uses electricity. The
load converts the electrical energy from the circuit into some other form of energy, such
as light or motion.
what is a switch - ANSWER-The switch is a device that is used to control the flow of
electrical current in the circuit. It can be used to turn the circuit on or off, allowing the
load to be powered or de-powered as needed.
two types of power supplies and schematic symbol - ANSWER-AC and DC
be able to interperate an electrical schematic which includes symbols - ANSWER-on
youtube look up engineering mindset- Single Phase Electricity Explained - wiring
diagram energy meter
resistor symbol - ANSWER-
Capacitor symbol - ANSWER-
inductor symbol - ANSWER-
ground symbol - ANSWER-
fuse symbol - ANSWER-
circuit breaker symbol - ANSWER-
lamp symbol - ANSWER-
switch symbol - ANSWER-
switch single pole double throw symbol - ANSWER-
normally open switch symbol - ANSWER-
