Electric charge

Question 1

What are 3 common materials that are electrical conductors?

Answer 1

1) copper
2) silver
3) aluminum.

Question 2

What are 3 common materials that are electrical insulators?

Answer 2

1) plastic
2) wood
3) rubber

Question 3

How can insulated materials be charged by friction?

Answer 3

Insulated materials can be charged by friction because friction can cause electrons to transfer between the materials

Question 4

What are some uses of electrostatic charges:

Answer 4

• in photocopiers
• inkjet printers

Question 5

What are the potential dangers of electrostatic charges?

Answer 5

Static electricity, or electrostatic charges, can be dangerous if they build up and discharge suddenly, causing sparks or shocks.

Question 6

Explain how electrons move in electrostatic phenomena

Answer 6

In electrostatic phenomena, electrons move primarily through friction and contact between materials, resulting in a transfer of charge.

Question 7

There are forces of ________ between unlike charges.

Answer 7

Attraction

Question 8

How are positive and negative electrostatic charges produced?

Answer 8

They are produced or materials by the loss and gain of electrons.

Question 9

There are forces of _________ between like charges

Answer 9

Repulsion.
