17
Q

What is a circuit

A

Is a complete path that electricity flows throw

18
Q

What happens to the light bulb if the circuit is open?

A

The wires somewhere are not connect. Therefore, the light bulb does not turn on.

19
Q

What happens to the light if it has an closed circuit?

A

The light bulb turn on.

20
Q

What are the 4 types of circuits?

A

-Open
-Closed
-series
-parallel

21
Q

What is a series circuit?

A

Series - one after another
There are no branch wires in the circuit.

22
Q

If there is a series circuit with two light bulbs, what happens to the second light bulb if the first bulb burns out?

A

The second light bulb will not work because the circuit is open. The burn out light bulb is no longer connected.

23
Q

If you want everything to work on a circuit after one component fails what type of circuit do you need?

A

Parallel Circuits

24
Q

What are the safety precautions when working with electricity?

A

1) Don’t use electrical stuff around water
2) do not plug too much in one outlet
3) don’t have wires under a carpet
4) watch out for electrical poles and wires

25
Q

A device used to control the flow of electricity

A

Light switch

26
Q

A measure of the amount of electrical energy supplied to each charge.

A

Volts

27
Q

The place which electricity enters or leaves an electrical component (battery).

A

Terminal

28
Q

A type of energy in which small particles (called electrons) move through a device.

A

Electricity

29
Q

A complete path for an electric current.

A

Circuit

30
Q

A device used for generating electricity through an electrochemical reaction.

A

Battery

31
Q

It is made of metal (often copper) ands used to make electricity circulate.

A

Electrical wire

32
Q

What is an atom?

A

Atom is the building blocks of all matter (everything living and not living)

33
Q

34
Q

What is in the Nucleus?

A

Protons and Neutrons

35
Q

What moves around the nucleus?

A

Electrons

36
Q

What part of the atom is positive?

A

Protons are Positive

37
Q

What parts of the atom is negative?

A

Electrons

38
Q

What part of the atom has no charge?

A

Neutrons “N” for No charge

39
Q

What is static electricity?

A

When an object gains or loses electrons it becomes electrically charged.

40
Q

How do you create static electricity?

A

You rub two things together to create fiction then the object gains or loses electrons.

41
Q

What are the parts of a battery?

A

Positive terminal
Negative terminal
Case

42
Q

What are the parts of a lamp / lightbulb?

A

Filament
