Q16 of 126 Page 196

Does a conductor become charged when a current is passed through it?

When a current pass through a circuit, the free electrons in the valence band of the conductor jump to the conduction band and drift throughout the conductor and as no extra electrons are provided to the conductor, the conductor does not get charged.

A metallic resistor is connected across a battery. If the number of collisions of the free electrons with the lattice is somehow decreased in the resistor (for example, by cooling it), the current will
