Metals are good conductors. True or false?

TRUE

1

Due to their type of bonding, metals have a:

- a fixed positive nucleus
- surrounded by a sea of electrons
- loosely held valence electrons are free to move

2

A salt solution conducts electricity. True or false?

TRUE

3

Insulator materials such as plastic and rubber have?

Electrons that are tightly bound. to individual atoms therefore there are no electrically charged particles that can move.

4

How is the amount of batteries affected by?

The more batteries the more electricity available

5

What is the amount of globes affected by?

The more bulbs, the more electrical energy is 'SAVED', thus each bulb has less.

6

In a SERIES CIRCUIT, components are connected one after another along what?

A series circuit components are connected along a SINGLE CONDUCTING PATHWAY.

7

In a PARALLEL CIRCUIT, each component is connected how?

In a parallel circuit, the components are SEPARATELY connected to the energy source. Each charge only passes though one source.

8

The brightness in light globes in electric circuits depends on what?

It depends on how quickly the energy flows through the globe.

9

What are the two factors that affect how quickly energy flows through the globe?

-The AMOUNT OF ENERGY EACH ELECTRON FLOWING THROUGH THE GLOBE HAS.

- the NUMBER OF ELECTRONS PASSING THROUGH THE GLOBE EACH SECOND.
