Terms 1
What are tiny particles that make up matter.
What is atoms?
A continuous flow of electrons
What is an electric current?
device used to drive screws into a material by turning it at the screw head
What is a screwdriver?
used to insulate wires that conduct electricity
What is electrical tape?
Are found in the center of the atom and have no charge.
What is anything that takes up space and has mass
What is matter?
Matter that carries electrons more easily than others
What is a conductor?
to pull and reposition wires in the electrical back boxes. They also use them to bend wires and make wire loops, as well as pick small wires in crowded electrical enclosures
What are long-nose (needle nose) pliers?
are designed to be locked closed, holding an object firmly without the need for the grip of a human hand
What are locking pliers?
Are materials that don't carry electrons easily
What are insulators?
What are found in the center of an atom and have no charge
What are neutrons?
Material that is neither a conductor nor an insulator
What is a resistor?
Twist over the bare ends of wires to make tight connections.
What are wire nuts?
provides protection against cuts and nicks caused by contact with electrical components.
What are insulated gloves?
This particle has a postive charge
What is a proton?
When an atom has an equal amount of both negative and postive charges
What is a neutral atom?
Where the electrons flow in and out of a battery
What are terminals?
a way to cut and remove the rubber coating that encases wire, but some of the best ones slice thick cable, cut screws to size, and crimp terminals onto the end of thick cables or wires
What are wire strippers?
What illuminates a dark area
What is a flashlight?
What is turn off the power at the breaker box?
Particles that orbit the nucleus of an atom and have a negative charge
What are electrons?
A path that is made for the electric current that must be complete path between two terminals of opposite charges.
What is a circuit?
safest tool to confirm that electrical power is off, even before you touch a wire.
What is a voltage tester?
used primarily for securing cables and wires in electrical installations and equipment
What are cable ties?
What color designates the hot wire?
What is black?
