- Which term best describes a material that allows electrical energy to pass through it?
- Resister
- Insulator
- Conductor
- Connector
- Which of the following best describes the term electrical cable?
- Any wire
- Any insulated wire
- Multiple wires grouped together in a common insulation
- Multiple insulated wires grouped together in a common sheathing
- What is the primary purpose of insulation on wires?
- To protect the wire
- To make installation easier
- To prevent unwanted current flow
- So the wire can be colour coded
- When is stranded wire used?
- On short wires
- When cost is a factor
- On straight runs of wire
- When flexibility is needed
- Wire is sized by gauge: the higher the number, the larger the wire.
- True
- False
- What should be done to stranded wire prior to bending?
- It should be curled.
- It should be tinned.
- It should be wound.
- It should be twisted.
- Solderless connections are more costly than soldering.
- True
- False
- What is one advantage to a twist-on connector?
- It is permanent.
- One size fits all.
- It will not come apart.
- It can be removed easily.
- It doesn’t matter what material the conductor is made from when making a connection.
- True
- False
- What type of connector should be used to create a permanent splice?
- Twist
- Winged
- Crimp-on
- Set screw
