SACA CERTIFICATION
can you define and test a ground? 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 1.Always use a circuit tester or voltage detector to check that a circuit is
de-energized before working on it.
electrical safety rule Never touch electrical wiring or equipment with wet hands or while
standing on a wet surface.
electrical safety rule Do not operate electrical equipment that is damaged, frayed, or otherwise
in poor condition.
electrical safety rule Use the correct fuse or circuit breaker for the circuit you are working on.
electrical safety rule Never remove or bypass the grounding prong on a plug.
Electrical Safety Do not use extension cords or multiple outlet adapters that are not rated
for the equipment you are using.
electrical safety Do not overload circuits by plugging in too many devices or using high-
powered equipment.
electrical safety Do not use electrical equipment in wet or damp conditions unless it is
specifically designed for that purpose.
electrical safety Use properly rated and properly installed surge protectors for sensitive
electronic equipment.
electrical safety Always follow the manufacturer's instructions for using electrical
equipment.
purpose of lockout tag out to prevent unexpected energization or startup of machinery or
equipment while it is being serviced or repaired.
state the two types of electrical current AC and DC
how to use a circuit tester 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 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 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 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 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.

knife switch a type of manually-operated electrical switch that is used to make and break
electrical circuits. It has a hinged blade that is used to open and close the contacts of the switch,
allowing the flow of electricity to be controlled.
push button switch a type of manual switch operator that is actuated by pressing a button.
When the button is pressed, the switch is turned on, and when it is pressed again, the switch is
turned off.
selector switch a type of manual switch operator that allows the user to select one of several
different circuit paths or positions. It is typically actuated by a lever or knob that can be rotated
or moved to different positions, each of which corresponds to a different circuit path or function.
explain the function of five types of output devices: resistor a passive electronic component that
resists the flow of electric current, reducing the voltage and current in a circuit.
explain the function of five types of output devices: fan a device that produces a flow of air,
typically using an electric motor. It is commonly used to circulate air in a room or to cool
electronic equipment.
explain the function of five types of output devices: lamp a device that produces light, typically
using electricity. It can refer to a light bulb or any other device that is used to produce light.
explain the function of five types of output devices: fuse a safety device that is used in
electrical circuits to protect against overcurrents. It consists of a piece of wire or other conductor
that is designed to melt and break the circuit if the current exceeds a certain level, preventing
damage to the circuit or injury to individuals.
explain the function of five types of output devices: transformer an electrical device that is
used to transfer electrical energy from one circuit to another. It typically consists of two or more
coils of wire, which are magnetically coupled to each other. When an alternating current flows
through one coil, it creates a varying magnetic field, which in turn induces a voltage in the other
coil, allowing electrical energy to be transferred from one circuit to the other.
