Understanding Electric Charge

What are the two types of electric charge?

• static and dynamic

• positive and negative

• positive and neutral

• negative and electric

What is the charge of an electron?

• -1.602 x 10^-19 coulombs

• -1 coulombs

• +1.602 x 10^-19 coulombs

• 0 coulombs

What is the charge of a proton?

• +1 elementary charge

• 0 elementary charge

• -1 elementary charge

• +2 elementary charge

Define a conductor in terms of electric charge.

• A conductor is a type of insulator that prevents electric charge from moving.

• A conductor is a material that blocks the flow of electric charge.

• A conductor is a substance that only allows magnetic fields to pass through.

• A conductor is a material that permits the flow of electric charge.

Give an example of a good conductor of electricity.

• Copper

• Plastic

• Wood

• Rubber

Define an insulator in terms of electric charge.

• An insulator is a type of electric charge itself.

• An insulator is a material that resists the flow of electric charge.

• An insulator allows electric charge to flow freely.

• An insulator is a material that conducts electric charge easily.

Give an example of a good insulator of electricity.

• Rubber

• Copper

• Iron

• Aluminum

What happens when two objects with opposite charges come into contact?

• The objects repel each other and increase their charges.

• The objects remain unchanged and do not interact.

• The objects explode upon contact due to energy release.

• The objects attract each other and may neutralize their charges.

How do conductors and insulators differ in terms of electron mobility?

• Conductors allow electrons to move freely, while insulators restrict electron movement.

• Insulators allow electrons to move freely, while conductors restrict movement.

• Conductors have no electrons, while insulators have many.

• Both conductors and insulators allow electrons to move at the same rate.

What is static electricity and how is it related to electric charge?

• Static electricity is the flow of electric current through a conductor.

• Static electricity is caused by the movement of protons in an atom.

• Static electricity is the result of magnetic fields interacting with electric charges.

• Static electricity is the accumulation of electric charge on surfaces due to an imbalance of electrons.
