Static Electricity vs Human-Harnessed Electricity

clothes sticking together in the dryer is an example of

• Static Electricity

• Current Electricity

A build up of electrical charges in an object

• Static Electricity

• Current Electricity

usually a sudden burst of electricty

• Static Electricity

• Current Electricity

You place a charged balloon next to a wall and let go. Which describes what will most likely occur?

• The negatively charged balloon will attract the positive charges in the wall, causing the balloon to stick to the wall.

• The negatively charged balloon will repel the positive charges in the wall, allowing the balloon to float away.

• The positively charged balloon will attract the positive charges in the wall, causing the balloon to stick to the wall.

• The positively charged balloon will repel the positive charges in the wall, allowing the balloon to float away.

Which statement best describes a difference between static electricity and current electricity?

• Static electricity is human-harnessed energy while current electricity is natural energy.

• Static electricity is created energy while current electricity is spent energy.

• Static electricity is natural energy while current electricity is human-harnessed energy.

• Static electricity is positive energy while current electricity is negative energy.

Which description best identifies the cause of static electricity?

• a lack of any neutral charges

• a lack of any positive or negative charges

• an imbalance of positive and negative charges

• an exact balance of positive, negative, and neutral charges.

When is it easiest for a person to build up static electricity?

• after a rainstorm when the air is warm and humid

• during the winter when the air is dry

• after a lightning strike when the air is full of electricity

• during the spring when the ground is wet

The pictures show two forms of electricity. Compared to static electricity, how do electrons move in current electricity?

• The electrons move freely.

• The electrons do not move.

• The electrons repel each other.

• The electrons are grouped in place.
