General Physics 2 Quiz

Which of the following is a key characteristic of a conductor?

• It resists the flow of electric current

• It allows electric current to pass through easily

• It completely blocks electric current

• It stores electric charge permanently

Which of the following materials is a good conductor of electricity?

• Rubber

• Copper

• Glass

• Plastic

Why are insulators used to cover electrical wires?

• To increase current flow

• To prevent electric shocks

• To allow more voltage to pass through

• To store electrical energy

Which of the following is an example of an insulating material?

• Aluminum

• Silver

• Rubber

• Iron

The main difference between a conductor and an insulator is:

• Conductors allow electricity to flow, while insulators do not

• Conductors resist electricity, while insulators allow it to pass

• Insulators generate electricity, while conductors store it

• Insulators increase current, while conductors decrease it

Which of the following processes involves charging an object by direct contact?

• Induction

• Rubbing

• Conduction

What is transferred when an object is charged by friction?

• Protons

• Neutrons

• Electrons

• Nucleus

An electric field is best described as a region where:

• Charges remain at rest

• Magnetic fields dominate

• A charge experiences a force

• The speed of light is constant

Coulomb's law states that the force between two charges is directly proportional to the product of their charges and inversely proportional to:

• Their individual masses

• The square of their distance

• The sum of their magnitudes

• The speed of light

Which of the following is the unit of electric charge?
