100
The space in which an electric force acts.
What is electric field.
100
The property of matter that causes objects to attract or repel each other.
What is electric charge.
100
A light bulb glows because of what inside the bulb?
What is filament.
100
A type of material through which negative charges can move easily.
What is conductor
100
This is made by wrapping current-carrying wire around an iron core.
What is electromagnet.
200
The build-up of charges on an object.
What is static electricity.
200
Matter that has a balance of positive and negative charges.
What is neutral charge.
200
What causes the devices in a series circuit to turn off?
What is a break in the circuit.
200
Negative charges of electricity flow easily through these.
What is conductor.
200
What is the effect of using two batteries instead of one on an electromagnet?
What is it gets stronger.
300
A circuit that has two or more paths that electricity can follow.
What is parallel circuit.
300
This type of charge moves from one object to another.
What is negative charge.
300
If one burned out bulb causes all of the lights to fail in a circuit, this is what kind of circuit.
What is series circuit.
300
A good insulator of electricity is a) saltwater b) plastic c) aluminum foil d) silver
What is b) plastic.
300
How can you make the magnetic field around a current-carrying coil of wire stronger?
What is wrap the coil around an iron core.
400
The measure of how much a material opposes the flow of current.
What is resistance.
400
The feeling you get when negative charges jump to the object you touch.
What is shock.
400
How is current electricity different from static electricity?
What is current electricity keeps moving around a circuit and static electricity separates charges and does not continually move.
400
A material that resists the flow of electricity is called what?
What is insulator.
400
What happens to an electromagnet when you remove the battery or power supply?
What is it stops working.
500
This occurs when current flows where it is not wanted.
What is short circuit.
500
One way objects can separate is by
What is rubbing two objects together or placing a charged object near a neutral object.
500
Adding more bulbs causes all of the bulbs to become dimmer. This is what circuit.
What is series circuit.
500
What type of material that we have mentioned is a good insulator?
What is plastic, wood, rubber, cardboard.
500
What item is missing from the list that should be included to make an electromagnet? battery, wire, paperclips
What is iron nail.
