Electricity Part 2

Question 0

Due to their type of bonding, metals have a:

Answer 0

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

Question 1

Metals are good conductors. True or false?

Answer 1

TRUE

Question 2

A salt solution conducts electricity. True or false?

Answer 2

TRUE

Question 3

Insulator materials such as plastic and rubber have?

Answer 3

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

Question 4

How is the amount of batteries affected by?

Answer 4

The more batteries the more electricity available

Question 5

What is the amount of globes affected by?

Answer 5

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

Question 6

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

Answer 6

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

Question 7

In a PARALLEL CIRCUIT, each component is connected how?

Answer 7

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

Question 8

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

Answer 8

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

Question 9

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

Answer 9

• The AMOUNT OF ENERGY EACH ELECTRON FLOWING THROUGH THE GLOBE HAS.
• the NUMBER OF ELECTRONS PASSING THROUGH THE GLOBE EACH SECOND.
