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

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

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.

When a potential difference is applied across a conductor, the free electrons in the conductor are set into motion. Two velocities are associated with the moving electron-the drift velocity and average velocity. The fact is that the two are :

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

A metallic conductor of irregular cross-section is as shown in the figure. A constant potential difference is applied across the ends (1) and (2). Then :
