equipped with different types of blades or
drill bit for concrete, wood, and metal
surfaces.
14. Electrical tape- This is used to wrap open wires
to avoid contacts with another wires. Main
purpose of electrical tape is for insulation of
connected open wire.
15. Cables and wires- This comes with different
gauge or sizes. They are important in
making electrical connections.
16. • Tester – an instrument used to test if there
is a flow of electricity in the connection
made.
17. Male plug- This is attached to one end of
a gadget and used to insert to a female
electrical socket to secure electrical
connection
18. Female outlet- This material is usually attached to the
wall of houses with ready electric supply, from which a
male plug is inserted to obtain electric supply.
Sometimes it is found on the other end of improvised
extension cord while male plug on the other end.
20. Health And Safety Practices In

convenience outlet or switch?
• I want to make an extension cord, what
electrical materials I am going to buy?
22. • What are the tools and materials
needed in making simple electrical
gadgets?
• What are the importance in using
tools and materials in making
electrical gadgets?
23. Always remember that:
Home repair are important
because they improve efficiency in
operating the house. It also costs
less to repair if maintenance is done
Doing some simple repairs use
the proper tools to avoid accident.
