Miscellaneous
100
An instrument that can detect, and sometimes measure the amount of, electric charges
What is an electroscope?
100
Magnet that can be INDUCED to have magnetic properties, but is not always magnetic
What is a temporary magnet?
100
Structures that provide paths through which electricity travels
What is a circuit?
100
The amount of potential energy that each unit of electrical charge has
What is voltage?
100
True or false. In a parallel circuit the current is the same throughout every part of the circuit.
What is FALSE?
200
Property of matter responsible for electrical events
What is electric charge?
200
Give an example of a permanent magnet.
What is a bar magnet, horseshoe magnet, refrigerator magnet, etc.
200
Type of circuit has more than one path for charges to flow.
What is a parallel circuit?
200
Opposition to the passage of an electric current
What is Resistance?
200
A substance that allows for the flow of electricity; most metals are good examples
What is CONDUCTOR?
300
The type of particle that moves in a wire to allow electricity to flow.
What is an electron?
300
A magnet that is created from current through a wire
What is an electromagnet?
300
Type of circuit that allows for only one path for charges.
What is a series circuit?
300
The quantity that refers to the rate of flow of electric charges
What is current?
300
Which holiday lights are better? EXPLAIN WHY!
What is PARALLEL, because if one goes out all the others will stay on. Each bulb has its own path back to the energy source.
400
True or false? Like charges attract, and opposite charges repel.
What is FALSE?
400
Magnets create this in the space around them and it exerts forces on other magnets
What is magnetic field?
400
A circuit with no breaks in it; electricity will flow
What is a closed circuit?
400
The unit for current
What is AMPERES or AMPS?
400
Describe how charge flows through a wire.
What is "electrons flow toward the terminal of the battery, exerting a force on other electrons (repel). This keeps occurring down the wire, until charges reach the positive terminal.
500
What are the two types of charges?
What is positive and negative?
500
The reason that we coil a wire around a piece of metal to make an electromagnet.
What is "to CONCENTRATE the magnetic field"?
500
Circuit that with a break in it. No charge will flow.
What is an open circuit?
500
Unit for resistance
What is OHMS?
500
Why does a power cord need two prongs?
What is "because one is going from the power source to the object needing electrical energy, while the other one is taking it back away from the object to the energy source. In creates a COMPLETE, CLOSED circuit"?
