When a light bulb is turned on, its thin wire filament heats up quickly. As the temperature of this wire filament increases, its electrical resistance

If 10 C of charge passes a given point in a conductor every 2 seconds, the current at that point is

Which changes would cause the greatest increase in the rate of flow of charge through a conducting wire?

If the diameter of a wire were decreased, its electrical resistance would

One coulomb per second is equal to one

Compared to insulators, metals are better conductors of electricity because metals contain more free

Copper is a metal commonly used for electrical wiring in houses. Which metal conducts electricity better than copper at 20C?

If the length of a copper wire is reduced by half, then the resistance of the wire will be
