When a potential difference is applied across the ends of a linear metallic conductor

What happens when a potential difference is applied across the ends of a conductor?

When a potential difference is applied across the ends of a conductor, how is the drift velocity of the electrons related to the relaxation time?

A potential difference is applied across the ends of a metallic wire. If the potential difference is doubled, the drift velocity will

When a potential difference is applied across, the current passing through

When a potential difference is applied across, the current passing through

When a potential difference of 2 volt is applied across the ends of a wire of 5 m length, a current of 1 A flows through it. Calculate : the resistance across the ends of the wire if it is doubled on itself.

A graph is plotted between the potential difference (applied across the ends of a conductor) and the current (following through the conductor). The graph is a straight line

Keeping the resistance constant, the potential difference applied across the ends of a component is halved. How does the current change?
