Current vs Static 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.

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.

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.

In a circuit, what is the purpose of the switch?

• to control the brightness of the light bulb

• to control the flow of energy through the circuit

• to prevent energy from going the wrong direction

• to prevent extra energy from building up in the circuit.

Match the following

• electron

• the build up of an electrical charge on an object from extra electrons

• neutron

• a particle with a negative charge that circles the nucleus of an atom

• current electricity

• a form of electricity where charges are able to constantly flow through a circuit

• proton

• a particle with no charge found in the nucleus of an atom

• static electricity

• a particle with a positive charge found in the nucleus of an atom

To get current electricity, you must have a path or circuit for the electrons to move.

• True

• False
