Unit 07 Electrostatics Review

Front

What is the process of charging a conductor by bringing it near another charged object?

Back

Induction

Front

Which material is not a good insulator?

Back

Copper

Front

In conduction charging, what happens to electrons when a charged metal bar is brought near a sphere?

Back

Electrons move from the charged metal bar into the sphere.

Front

What happens to the atoms in an insulator when a positively-charged plate is brought nearby?

Back

The atoms polarize, with negative charges moving towards the positive plate.

Front

If Sphere A has a charge of +8 coulombs and Sphere B has a charge of -6 coulombs, what will be the charge on Sphere A after they are touched together and separated?

Back

+1 coulomb

Front

Define electrostatics.

Back

The study of electric charges at rest.

Front

What is polarization in the context of electrostatics?

Back

The separation of charges within an object, leading to a positive and negative side.

Front

What is an insulator?

Back

A material that does not allow electric charges to flow freely.

Front

What is a conductor?

Back

A material that allows electric charges to flow easily.

Front

Explain the principle of conservation of charge.

Back

The total electric charge in an isolated system remains constant.
