B.5 - 3 Resistance and Resistivity

What is resistance?

• The amount of current flowing through an object.

• The amount of opposition current will experience to its flow.

• The amount of voltage lost per charge.

• The amount of energy gained by current.

What is the standard unit for resistance?

• Volts

• Amps

• Ohms

• Meters

What is resistivity?

• The total resistance of a material.

• The amount of resistance a given cross-sectional area of a material will experience per unit of length.

• The rate at which current flows through a material.

• The voltage drop across a material.

How does the resistance of a material change with its length and cross-sectional area?

• Resistance increases with length and decreases with cross-sectional area.

• Resistance decreases with length and increases with cross-sectional area.

• Resistance increases with both length and cross-sectional area.

• Resistance decreases with both length and cross-sectional area.
