Electrical Theory & Application For
HVACR Questions And Answers With
Verified Solutions Already Passed!!!
What is current flow?
ANSWER: The flow of electrons in a circuit.
Current flow refers to the movement of electrons through a conductor, forming an
electrical current.


What is impedance?
ANSWER: Opposition to alternating current flow.
Impedance is a combination of resistance and reactance in a circuit, specifically
opposing the flow of alternating current (AC).


Any material that will readily release electrons is called:
ANSWER: A conductor.
Conductors, like metals, allow electrons to flow freely and easily, enabling electric
current to pass through.


The symbol for current is:
ANSWER: I.
The letter "I" is used to represent electric current in equations.


Electricity can produce:
ANSWER: Heat, light, magnetism.
Electricity can be converted into different forms of energy, such as heat (in
heaters), light (in bulbs), and magnetism (in electromagnets).


The safety ground conductor is usually color-coded:
ANSWER: Green.

, The ground conductor is typically green or bare to indicate it is used for safety
grounding.


An electron:
ANSWER: Has a negative charge.
Electrons carry a negative charge, which is important for electrical current flow.


What is resistance?
ANSWER: Opposition to current flow.
Resistance opposes the flow of electrical current in a circuit.


What type of meter uses its own battery?
ANSWER: Ohmmeter.
An ohmmeter uses its own internal battery to measure resistance in a circuit.


A black-colored wire usually indicates:
ANSWER: A hot wire.
In most wiring systems, black wires are used to carry current from the power
source and are considered "hot" wires.


How are fuses sized?
ANSWER: By amperage and voltage.
Fuses are rated based on the maximum current (amperage) they can handle and the
voltage they can withstand.


What is generally the maximum supply voltage variation?
ANSWER: 5%.
Voltage supply can fluctuate by up to 5% from the nominal voltage level.
