Front 15

If you were asked to wire a house in a series circuit or a parallel circuit, what would you chose?

Back 15

Parallel, because if one bulb goes out, they don't all go out

True or false, static electricity describes an electric charge that is stationary on the surface of a material

Back 16

False, it is not only on the surface

Front 17

True or false, charged objects attract neutral objects

Back 17

True

Front 18

Why do some household appliances have three prongs?

Back 18

It helps protect against electric shocks and fires by connecting to the grounding wire

Front 19

Why do neutral objects attract to charged objects?

Back 19

An induced charge on the object

Front 20

What are the two types of charging?

Back 20

Induction (not touching)

Contact (touching)

Front 21

Why do bulbs go dimmer in a series circuit when more are added?

Back 21

Because the loads share electrons in series circuits

Front 22

Using words, how would you describe the symbol for a motor

Back 22

Line->Circle with M in it->Line

Front 23

What is the job of resistors?

Back 23

They allow some electrons to flow through but not all

Front 24

Why do batteries end up not working after some time?

Back 24

They run out of chemicals

Front 25

Why is it that birds don't get electrocuted when they sit on power lines?

Back 25

They're bodies don't complete a circuit

Front 26

What is a conducting wire?

Back 26

It carries the electrons from the source to the load and back to the source

Front 27

What is a load?

Back 27

This changes electrical energy o other forms of energy

Front 28

What is a source?

Back 28

The main provider of electrons for the circuit

Front 29

What is a switch?
