Static vs. Current Electricity

Which statement best describes what will happen as negatively charged electrons move from the cloth to the balloon?

• The cloth will become positively charged, and the balloon will become neutral.

• The cloth will become negatively charged, and the balloon will become neutral.

• The cloth will become positively charged, and the balloon will become negatively charged.

• The cloth will become negatively charged, and the balloon will become positively charged.

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

When two objects are rubbed together, some negatively charged particles from one object can be transferred to another object. What will happen if the objects have the same charge?

• They will create a spark.

• They will not act differently.

• They will attract each other.

• They will repel each other.

Which examples below describes naturally-occurring electricity?

• battery

• current electricity

• Quick release of energy

• Getting shocked when plugging in a vacuum cleaner

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.

All circuits need to have a source of power and a load. What is a good example of a load?

• copper wire

• battery

• switch

• toaster

Thomas created the circuit pictured below using a battery, a switch, and a wire connected to a light bulb. The light is not coming on. What is most likely the reason the bulb is not lit?

• The battery is not connected correctly.

• The bulb is broken.

• The circuit is open.

• The wire is not conducting electricity.
