RESISTANCE

The amount of______in a wire is influenced not only by the voltage on both of its ends but also by the resistance of the wire.

• CURRENT

• RESISTANCE

• VOLTAGE

• CHARGES

The opposition of a material to the flow of charges

• CURRENT

• RESISTANCE

• VOLTAGE

• CHARGES

The SI unit for resistance is the______.

• COULOMBS

• OHM

• AMPERE

The measure of resistance of a specific material for a given dimension.

• RESISTANCE

• RESISTIVITY

NGSS.HS-PS2-5

Materials considered as insulators, such as wood and amber, have significantly low resistivities

• TRUE

• FALSE

NGSS.HS-PS2-6

The resistivity of a metallic conductor, and its resistance, generally decreases with increasing temperature

• TRUE

• FALSE

Some metallic materials and alloys have a property called superconductivity. Initially, the resistivity of these materials increases as the temperature is increased.
