Multiple Choice

are constructed of one, single piece of metal. It is tougher than a stranded conductor, but rigid and less flexible than a stranded conductor. Solid conductors are more likely to break if subjected to frequent flexing than stranded conductors

• Solid conductors

• Stranded conductors

• Solid insulators

• Stranded insulators

Multiple Choice

it is either a stranded conductor (single‐conductor cable) or a combination of conductors insulated from one another (multiple‐conductor cable).

Multiple Choice

It is a conductor composed of a group of wire or any combination of group of wires. The wires in this conductor are usually twisted together and not insulated from each other.  

• Solid conductors

• Stranded conductors

• Cable conductor

• Stranded insulators

Multiple Choice

it is a device used to break an electric current or transfer it to another conductor. commonly used to open or close a circuit. Closed is the ON position, while open is OFF position.
