With the motor running at full load the contact between T1 and L1 indicates no voltage this is an
indicator of - ANS This shows that the contacts are good
Impedance is - ANS Opposition to alternating current flow
1 HP equals how many watts? - ANS 746 watts
Symbol for current - ANS I (amps)
Which is the correct formula for determining wattage in electrical circuit - ANS P equals E times
I
ECM motor speed is controlled by: - ANS Pulses of DC power sent by the control module to the
windings.
The three essential requirements for a useful electric circuit are - ANS A power source a pass
for current flow and an electrical load
The typical voltage of a thermcouple - ANS 30 MV/DC
Name a type of inductive load - ANS A three phase motor
True or false /the current flows through a conductor does not produce a magnetic field unless
the wire is coiled - ANS False
Three phase load requires a minimum of - ANS Three legs of power
In an AC capacitive circuit - ANS Current leads voltage
When replacing fuses be sure to match - ANS The voltage amperage instantaneous current
and class
, Variable frequency drives reduce the speed of AC motors by - ANS Controlling the frequency of
the power to the motor
A heat pump defrost control must do three things - ANS Turn on auxiliary heat turn off the
condenser fan motor and shift the reversing valve from heat to cool
Hey normally open set a really contacts will close when - ANS Power is applied to the relay coil
When hopscotch troubleshooting follow the schematic and move the meter lead on the control
side of the circuit from one control to the next checking the voltage in and out of the control the
voltage will be ________ immediately after the control that is opening the circuit - ANS 0 V

primary voltage is 120 V what would be the secondary voltage - ANS 24 V
current flow is - ANS The flow of electrons in a circuit
Why are capacitors rated higher voltage than the unit line voltage - ANS Charging and
discharging in series with an inductive load subjects them to high voltage
When resistors are wired in parallel - ANS The voltage will be the same
High resistant problems can be detected by - ANS Checking the voltage drop across switches
and checking current flow
Compared to the run winding the start winding is constructed of - ANS Smaller gauge wire than
the run winding
There will be no continuity between the primary and secondary side of a transformer if the
transformer is a set up - ANS False
What is the voltage between the stinger leg of a delta transformer and ground - ANS 208 V
