2 ways an electromagnet is like a regular magnet.
What are they both attract metal objects, they both have poles, both have a magnetic field.
200
What will happen if you add another bulb to a series circuit?
What is no, because there is no power source for this circuit.
300
Among these materials, which are both conductors?
A)Rubber and copper B) Cotton and silver C) Wood and paper D) Copper and aluminum

What is A
300
Which is more useful in a home - a series circuit or a parallel circuit? Why?
What is a parallel circuit because it provides more than one path for electricity to follow, so every device in the house does not have to be on at the same time.

What is D) They have opposite charges.
400
3 items needed to build a circuit?
What are a path for the electricity to follow (wire), a power source (battery) and a device to use the electricity (load)?
400
The best place to use an insulator in an electric circuit?
What is around the wires to keep the electricity where you want it.
400
2 ways you can make an electromagnet stronger.
What are add more coils to the wire, add more power (add an additional battery).
400
In a parallel circuit with 2 light bulbs, what will happen if one of the bulbs burns out?
What is the other bulb will continue to light up because there is an alternate path for the electricity to follow.
500
