Q

What is a short circuit? How is it caused?

A

Occurs when an electrical connection is made where it shouldn’t be.

For example: wires touch when they shouldn’t, or water touches the circuit, causing the circuit to overheat.

Q

What is a fuse? Can they open or close a circuit? Why are they important?

A

A fuse a thin piece of metal that can interrupt the flow of electrons. Fuses open the circuit because they overheat and burnout causeing a gap. They act as a safety feature to prevent shirt circuits and overheating.

Q

What materials make the best conductors of electricity?

A

metals, such as silver, gold, copper, and aluminum

22
Q

How is a series circuit different from a parallel circuit?

A

A series circuit only has one path, but a parallel circuit has different paths for the electricity to flow.

23
Q

A _____ is a pathway through which electricity flows.

A

circuit

24
Q

When you turn the switch “on”, the circuit is _____ and the path is unbroken (electricity will flow through it).

A

closed

25
Q

When you turn the switch to “off”, the path is _____ or broken (electricity stops flowing).

A

open

26
Q

A circuit has a switch, a wire, a battery, and a bulb. When the switch is flipped, the light turns on because of the energy supplied by the battery. Which energy is used in this circuit when it is closed?

A

Chemical energy from the battery is transformed into light energy.

27
Q

Mrs. Smith rubbed an air-filled balloon on her hair. She then touched the balloon to the wall and the balloon stuck to it. What made the balloon stick to the wall?

A

The static electricity on the balloon had an opposite charge as the wall, so the opposite charges attract and the balloon stuck to the wall.

28
Q

_____ electricity is caused by a build up of charge, while current electricity happens when electricity _____.

a. Positive; negative
b. Electromagnet; circuit
c. Static; flows
d. Circuit; conductor

A

c. Static; flows STATIC electricity is caused by a build up of charge, while current electricity happens when electricity FLOWS.

29
Q

Four light bulbs are connected in a series circuit. What will happen to the other bulbs one of them burns out?

A

The rest of the bulbs will go out (will not light) because the circuit has been interrupted.

30
Q

Four light bulbs are connected in a parallel circuit. What will happen to the other bulbs if bulb 2 and bulb 3 burn out?

A

The other two bulbs will continue to light, because a parallel circuit has multiple paths for the electricity to flow.

31
Q

Name three materials that are good electrical insulators.

A

glass, plastic, and rubber are good insulators

32
Q

_____ is a form of electricity in which electrical charges collect on a surface of an object.

Q

A material that slows or stops the flow of electricity is called a/an _____. a. insulator b. circuit c. conductor d. charge

A

Insulator

35
Q

A temporary magnet that is made by an electric current is called a/an ______. a. insulator b. conductor c. permanent magnet d. electromagnet

A

Electromagnet

36
Q

_____ is a form of electricity in which electrical charges move from one place to another.

a. Current electricity
b. Static electricity
c. Moving electricity
d. Electromagnets

A

Current electricity

37
Q

What types of charges attract? What types of charges repel?

A

Opposite charges attract; Like charges repel.

38
Q

What is a conductor?

A

A conductor is a material that lets electrons flow through it easily.

39
Q

What is a parallel circuit?

A

A parallel circuit has two or more paths for the electrons to flow.

40
Q

What is an insulator?

A

An insulator does not allow electrons to flow through it.

41
Q

What is a resistor?

A

A resistor slows down the flow of electrons.

42
Q

What is a series circuit?

A

A series circuit has only one path for electrons to flow through.

43
Q

What is static electricity?

A

Static electricity is a build up of electrons.

44
Q

What is current electricity?

A

A flow of electrons?

45
Q

What is an electrical current?

A

An electrical current is when the electrons flow or move.

46
Q

Explain static electricity.

A

Build up of electrons.

47
Q

Explain current electricity.

A

Flow of electrons.

48
Q

What is a conductor?

A

Something that lets electricity pass.

49
Q

What happens when a series circuit has two light bulbs and one dies?

A

The whole circuit shuts down since the pathway is inerrupted.

50
Q

What is a conductor? Give me some examples.

A

Is something that allows electricity to flow. Most metals: copper, aluminum, graphite, and even water are good conductors.

51
Q

An electrical _______ is when the electrons flow or move.

A

Current
