The resistance high in a short circuit?
True
False
When reassembling your appliance ground wire requires which of the following? Check all that apply.
Reconnect the ground wire to the cabinet
Make sure metal physical connections are made
Do not worry about the ground wire and just put appliance back together
What is a short circuit? Check all that apply.
Two bare conductors come in contact with each other
Wire is short so it can fit in a small/cheaper cabinet
This circuit have very little resistance between both sides of the power source (battery, wall power)
What are main components of a circuit? Check all that apply
Power source
Load
Control device such as switch
Conductors
Safety device such as fuse
What happens when an open circuit occurs? Check all that apply
Conductor or component breaks stopping flow of electricity
Like opening a switch
What do you do when testing a motor taken out of an appliance? Check all that apply.
Find a fuse and fuse holder to match the motor's rating (Get from data on the motor's model number)
Build a circuit with switch, fuse and motor
Figure out the rating of the motor, voltage (AC or DC), current, number of speeds and phase
Connect motor directly to a power source matching the motor and check
Check model number and motor supplier's website to see if the motor has thermal protection
