The round prong of a plug that connects any metal pieces in an appliance to the safety grounding wire of a building.
What is a Third Prong
100
Unit for current.
What is Amps
100
Protons are + charges and _________ are -.
What is electrons.
100
(A) times (ohms) =
What is what is V or voltage.
100
It melts when in gets hot to prevent its device from catching fire.
What is fuse.
200
The continuous flow of electric charges through a material.
What is Electric current.
200
Conductors
What is a material though which charge can flow easily.
200
Charges that are opposite ________ each other.
What is attract.
200
An open switch ____ a circuit.
What is breaks.
200
Voltage multiplied by current.
What is power
300
Static electricity
What is the build up of charges on an object.
300
When charges are made to flow through a a material.
What is an electric current.
300
Static discharge
What is the loss of static electricity as electric charges transfer from one object to another.
300
How series and parallel differ.
What is
Series circuits have only one path for current to take, therefore if one light goes out and blocks the path for the rest of the current to take. So when one light goes out in a series circuit all the lights go out. When lights are added the rest of the lights get dimmer because when each light is added resistance increases.
Parallel circuits have more than one path for a current to take therefore when one light goes out the other light bulbs don't go out because the charge can still flow. When a light bulb is added to this circuit the resistance actually decreases and the brightness stays the same.
300
The usual unit of electric energy usage.
What is Kilowatt- hours.
400
Define short circuit.
What is a connection that allows current to take a path of least resistance.
400
A complete unbroken path charges can move through.
What is electric current.
400
Four methods by which charges can redistribute themselves to build up static electricity.
What is Friction, Conduction, Induction, and Polarization.
400
Ohm says that current, resistance, and voltage are all related in the ____ way.
What is same.
400
Two ways to prevent electric shock.
What is redirecting current and breaking currents.
500
How do atoms differ in insulators or conductors.
What is atoms in conductors have loosely bound atoms so charges can move freely through the object and in insulators they are more tightly bound making it more difficult for charges to to move through the object.
500
Field lines point _____ from positive charges.
What is away
500
Electric circuits all these features.
What is devices that run on electrical energy, sources of electrical energy, and conducting wires. ( switches sometimes)
