Name the four things needed for a complete circuit.

1. Power source/ supply

2. Path 

3. Switch

4. Load 

100

In the Atom which particle is negatively charged?

The Electron

100

Explain a contactor

key words I'm looking for

coil 

magnetic 

bridge for electricity

:this will be at my discretion:

100

The part the rotates

The Rotor

100

This device sends a electrical charge from the meter to read resistance.

The ohmmeter 

200

In a series circuit what stays the same through out the circuit?

The Amperage (Current)

200

In an Atom what particle is positively charged?

The proton

200

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:

200

The part that is stationary

The Stator 

200

This device is to test the insulation of the wired windings 

The meg-ohmmeter 

300

In a parallel circuit what stays the same through out the circuit?

The Voltage (Volts)


300
What is read when reading voltage?

potential difference 

300

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:

300

More poles on a motor does what to the rpm 


RPM goes down

300

This device reads in potential difference

The voltmeter

400

In a parallel circuit what would be total resistance with 4 ohms, 5 ohms, 20 ohms.

2 OHMS

 


400

An Atom with excess Electrons is what?

negatively charged

400

What part would be used as a timing device for heat strips?

A heat sequencer 

400
This motor runs at very high efficiency for single-phase motor. This motor is a brushless DC motor operated by an attached variable frequency drive. 

ECM (Electronically Commutated Motor)

400

This device is used to Manuel connect contacts to create call.

Wire jumpers

500

In a series circuit what is the total resistance if the resistors read: 5 ohms, 5 ohms, 5 ohms

15 OHMs

500

All Atoms all want to be?

Neutral (back to stable)

500

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

500

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.

500

This device is used to help solve problems with the unit. It can help with getting information at a moments notice
