This document discusses four common electrical materials: flat cord which is a stranded wire used for temporary wiring installations like extension cords; electrical wire/conductor which can be either stranded wire made of multiple joined strands or solid wire made of a single strand; electrical tape used to insulate electrical wires; and solder, a fusible metal alloy used to join wires together.

stranded wire used
for temporary
wiring installation
and commonly used

3. in extension cord
assembly.

4. 2. Electrical
Wire/conductor
(TW)-electrical wire
could be:

5. a. Stranded wire-
made of multiple
strands joined
together to make a
single wire.

6. b. Solid wire-is
made of a single
strand of copper or
aluminum wire.

8. 3. Electrical tape-
used to insulate
electrical wires.

10. 4. Solder-a
fusible metal
alloy used to join
wires together.
