Electrical Safety
Working Barefoot is fine when working with Electricity
What is False
You should have rubber based footwear which works as an insulator in case of emergency.
Unit the measures pressure in the wire
What are volts?
The amount of electricity used by an item
What are amps
Rubber or Plastic surrounding a wire
What is an insulator
Watt total if 10 amps and 12 volts
What is 120 Watts
Fuses should always be labeled
What is true?
It helps to make sure that you have turned off the proper breaker before working on an electrical device
The amount of volts that run through most small appliances
What are 120 Volts
True or False
An item must have a proper wire to work.
True
The highest metal conductor
What is silver
True or False It is best to work with electricity in very cold weather. Keeps things from overheating
What is false. It actually creates condensation which acts as a conductor.
For daily use pulling a plug by the cord is a good idea as it keeps you away from the electrical socket.
What is false? Pulling a cord can damage the wiring as well as the socket.
The amount of Volts that begin to get dangerous for a human
What are 24 volts
Too small a wire for an appliance will cause this
What is Overheating, Burning out the item
Dry Wood Insulator or Conductor
What is insulator
An electric current that reverses its direction many times a second at regular intervals.
What is an AC current (Alternating current)
There is no such thing as electric burn.
What is false?
Electric burn can happen when a wire overheats from having to much force for the wire's capabilities.
True or False
Volts measure the amount of electrons freely running through a wire
True
True or False
Most houses are wired for 5000 amp service
What is false. Most houses are wired for 220 service
measure of the difficulty of passing an electric current through a substance
What is resistance
When using a jumper cable to charge a battery, electric burn from a potential spark is the biggest concern True or False
True, more dangerous than potential electric shock.
Always use two hands when working with electricity as it helps you grip better.
What is false. We are conductors and by using 2 hands you may keep a circuit flowing.
How do you calculate Volts when you know amps and resistance
Amps times resistance
V=IxR
Volts/Resistance
What are Amps
I=VxR
Metals and plasmas that readily lose and gain electrons
What is a conductor
An electric Current that only flows in one direction. Similar to a river.
What is a D/C Current
