Glossary Of Terms III

Question 1

Centrifugal Switch

Answer 1

Switch on the motor shaft that opens or closes in relation to motor speed.

Question 2

Impedance

Answer 2

Total opposition to current flow which is the summation of total actual resistance, capacitive reactance, and inductive reactance in an alternating current circuit.

Question 3

Induced Voltage

Answer 3

Voltage produced in a circuit by the changes in number of magnetic lines of force that cut across a conductor

Question 4

Inductance

Answer 4

Inherent property of an electrical circuit whereby energy is stored in a magnetic field

Question 5

Inductive Reactance

Answer 5

Opposition to change of current that causes the out-of-phase condition of volts and amps

Question 6

In Phase

Answer 6

Condition when sine waves values of like polarity peak in magnitude at the same time

Question 7

In-Rush Amperes

Answer 7

Amps produced in the run winding when the motor is first energized and is four times greater than normal running amperage

Question 8

Locked Rotor Amps (LRA)

Answer 8

The condition of current flow which occurs as In-Rush amps to start the rotor rotating from its locked position

Question 9

Motor

Answer 9

Electrical device that converts electric energy to mechanical energy by magnetism to create a rotating motion to drive components of work

Question 10

Out-of-Phase

Answer 10

Condition of alternating current when the magnitudes of sine waves of like polarity reach maximum values at different times
