HPS Electricity and Circuits Review

A proton has a __________ charge.

• positive
• negative
• neutral

A neutron has a __________ charge.

• positive
• negative
• neutral

An electron has __________ charge.

• positive
• negative
• neutral

In Picture 1, what kind of charge does the balloon have?

• positive charge
• negative charge
• no charge

In Picture 1, what kind of charge does the cloth have?

• positive charge
• negative charge
• no charge

In Picture 1, what would the reaction be between the balloon and the cloth?

• They would attract each other since they have opposite charges.
• They would repel each other since they have the same charge.
• They would not attract or repel since neither object is charged.

In Picture 2, what kind of charge does the balloon have?

• positive charge
• negative charge
• no charge (neutral)

In Picture 2, what kind of charge does the cloth have?

• positive charge
• negative charge
• no charge (neutral)

In Picture 2, what would the reaction be between the balloon and the cloth?

• They would attract each other since they have opposite charges.
• They would repel each other since they have negative charges.
• They would not attract or repel since neither object is charged.

Choose the statement that correctly explains the movement of charged particles between the balloon and the cloth. **Keep in mind there is only one particle of an atom that has the ability to move from one atom to another.

• The protons are pulled from the balloon to the cloth, making the cloth positively charged.
• The electrons are pulled from the balloon to the cloth, making the cloth negatively charged.
• The protons are pulled from the cloth to the balloon, making the balloon positively charged.
• The electrons are pulled from the cloth to the balloon, making the balloon negatively charged.
