Static Electricity

Question 1

Electricity

Answer 1

Energy transferred by charged particles

Question 2

Static electricity

Answer 2

• caused by a build up of imbalanced charged particles

- usually on an insulated material because the charge cannot easily flow

Question 3

Conductor

Answer 3

-Conducts charge well

Question 4

Insulators

Answer 4

Does not conduct charge well

Question 5

Static charge

Answer 5

Build up of imbalanced charge on material due to friction

Question 6

Electric field

Answer 6

• surrounds a charged object
• decides which direction of the force will go when object come close
• I.e attract or repel

Question 7

Protons

Answer 7

• Positive charge in atoms

- found in nucleus

Question 8

Electrons

Answer 8

• negative charge in atoms

- found on the outside

Question 9

Neutrons

Answer 9

• neutral charge in atoms

- found in nucleus

Question 10

Charge of atoms

Answer 10

No charge

-the charges cancel out leaving them neutral

Question 11

What happens to the charge when friction occurs

+ why does this not happen to conductors

Answer 11

-only electrons transfer
-this imbalances the charge
+ conductors never have a build up of charge as they flow right back to the original objects

Question 12

Process of static electricity

Answer 12

• insulating materials rub together, electrons transfer from one object to the other and can’t make their way back
• leaving more protons in one objects and more electrons in the other = they have opposite charges
• the two objects attract each other

Question 13

What is lightening

Answer 13

• imbalance of charges in the clouds (due to many reasons I.e weather)
• this discharges from the clouds to Earth due to attraction

Question 14

What is a spark

Answer 14

• when the gap between negative charge and Earths objects is large enough
• the electrons can jump across the gap = producing a spark

Question 15

Use of static electricity

Answer 15

• laser machines
• photo copiers
• Heart defibrillators
• spray painting cars
• filtering factory smoke
