Level 2 HVAC Module 1 Alternating
Current
Alternator - Correct Answer an electric generator for producing alternating current.
Arc flash - Correct Answer is the extreme heat and light which can occur while working on live electrical parts.
Armature - Correct Answer is the rotating part of an electrical generator.
Capacitor - Correct Answer is a electrical storage device containing two metal plates separated by an insulating
material.
Capacitor-Start motors - Correct Answer is a type of motor with a capacitor in the starting circuit.
Dielectric - Correct Answer an insulator; a term that refers to the insulating material between the plates of a capacitor.
Induction - Correct Answer is to generate a current in a conductor by placing it in a moving magnetic field.
Megohmmeter - Correct Answer instrument that measures large amounts of resistance and is used to test electrical
conductor insulation.
Microfararad - Correct Answer is used to rate capacitors.
Rotor - Correct Answer is the rotating component of an induction motor.
Run winding - Correct Answer the winding that keeps the motor going.
Shaded-Pole motor - Correct Answer is a induction type of motor that does not incorporate an ordinary type of
starting winding.
Sine wave - Correct Answer is the waveform created by an AC generator.
Torque - Correct Answer is the force that must be generated to turn a motor.
Transformer - Correct Answer is a device that increases or decreases the voltage of alternating current.
