100
what is an example of a conductor of electricity?
what is copper, paper clip, wire,
100
what do you need to make an electromagnet?
coil of wire, nail, battery
100
How much a material opposes the flow of current
What is resistance?
200
What are electric charges that move?
what are negative charges?
200
What is a closed path that an electric current follows?
What is an electric circuit?
200
what is an example of an insulator of electricity?
what are rubber, wood, paper, styrofoam, plastic
200
what part of the items used in making the electromaget is the magnet?
what is a nail?
200
which has more resistance, thin wire or thick wire?
what is thin wire
300
When matter has an equal number of positive and negative charges, what kind of charges does it have?
what are neutral charges?
300
What causes a device in a circuit to turn off?
What is a break in a circuit?
300
What is a conductor?
A type of material through which negative charges move freely
300
What is an iron core with a current-carrying wire coiled around it.
what is an electro-magnet?
300
How is an electromagnet like a bar magnet?
They both have a north and south pole
400
When you take clothes out of a dryer you get shocked. What causes this?
What is static electricity?
400
What is the difference between a parallel and series circuit?
What is a circuit with only one path-series circuit, What is a circuit with 2 paths - parallel circuit
400
What is an insulator?
What is a material that resists the flow of electricity?
400
In the electromagnet, we discussed in class, why does the wire pick up paper clips?
Because the wire is wrapped around the nail and attached to a source of electricity-battery
400
After rubbing a paper towel on plastic wrap, why would one side of the plastic wrap repel the other?
One side has more positively charged particles than the other.
500
what is the space in which an electric force acts?
What is an electric field?
500
What is a break in the circuit?
What causes the device in a circuit to turn off?
500
why do electrical appliances contain both conductors and insulators?
conductors so the current can flow and make the appliance work. insulators to keep people from touching the conductors and getting shocked.
500
how can you make the current around an electromagnet stronger?
wrap the wire tighter or add another battery
500
why wouldn't the light bulb light when the wire was not attached to both ends of the batty
it was not a closed circuit.
