HW 1 Discovery of Electricity

Front

What is the force that tends to push electrons away from the nucleus?

Back

Centrifugal force.

Front

What is ionization?

Back

The gain or loss of one or more valence electrons.

Front

What is an insulator?

Back

A material that does not allow electrical current to flow easily.

Front

What is a conductor?

Back

A material with many free electrons.

Front

What is voltage (E)?

Back

The measure of electric potential energy per unit charge between two points.

Front

What is electrostatic attraction?

Back

The force that pulls electrons towards the nucleus.

Front

What is the role of free electrons in a conductor?

Back

They allow electricity to flow easily through the material.

Front

What is resistance in an electrical circuit?

Back

The opposition to the flow of electric current.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow easily, while an insulator does not.

Front

What is the unit of voltage?

Back

Volt (V).
