In the Atom which particle is negatively charged?
The Electron
Explain a contactor
key words I'm looking for
coil
magnetic
bridge for electricity
:this will be at my discretion:
The part the rotates
The Rotor
This device sends a electrical charge from the meter to read resistance.
The ohmmeter
In a series circuit what stays the same through out the circuit?
The Amperage (Current)
In an Atom what particle is positively charged?
The proton
Explain a Transformer
words looking for:
iron plates electrical field
step up and or step down coil windings
secondary and primary
:This will be at my discretion:
The part that is stationary
The Stator
This device is to test the insulation of the wired windings
The meg-ohmmeter
In a parallel circuit what stays the same through out the circuit?
The Voltage (Volts)
potential difference
Explain A Capacitor
words I'm looking for:
storage discharge plates resistance
higher Volts pulse start capacitor
run capacitor
:This will be at my discretion:
More poles on a motor does what to the rpm
RPM goes down
This device reads in potential difference
The voltmeter
In a parallel circuit what would be total resistance with 4 ohms, 5 ohms, 20 ohms.
2 OHMS
An Atom with excess Electrons is what?
negatively charged
What part would be used as a timing device for heat strips?
A heat sequencer
ECM (Electronically Commutated Motor)
This device is used to Manuel connect contacts to create call.
Wire jumpers
In a series circuit what is the total resistance if the resistors read: 5 ohms, 5 ohms, 5 ohms
15 OHMs
All Atoms all want to be?
Neutral (back to stable)
What part is used to close or open contacts. This device can be found on Control boards, before motors, and in heat strips assemblies.
The Relay
On a 3 phase motor, if the shaft is spinning the wrong direction how can I correct this.
By swapping any two of the wires on the load side either at contactor or in motor.
This device is used to help solve problems with the unit. It can help with getting information at a moments notice
