Understanding Number Density

What is the definition of number density?

• The mass of charge carriers in a unit volume

• The volume of a single charge carrier

• The number of charge carriers per unit volume

• The number of atoms in a molecule

How is the number density symbolized in mathematical terms?

• Uppercase V

• Lowercase v

• Uppercase N

• Lowercase n

What are the units of number density?

• Meters squared

• Kilograms per cubic meter

• Cubic meters

• One over meters cubed

In a volume of one cubic meter, if there are three charge carriers, what is the number density?

• 4 m^-3

• 3 m^-3

• 2 m^-3

• 1 m^-3

For a volume of 2x2x2 meters with three charge carriers, what is the number density?

• 0.4 m^-3

• 0.5 m^-3

• 0.375 m^-3

• 0.25 m^-3
