If the length of a wire conductor is doubled by strctching it while keeping the potential difference constant, by what factor will the drift speed of the electrons change?

If the length of a wire conductor is doubled by stretching it, keeping the potential difference across it constant, by what factor does the drift speed of the electron change?

If the length of a wire conductor is dobled by stretching it, keeping the p.d. across it constant by what factor does the drift speed of electrons change?

If the length of a wire conductor is doubled by stretching it, keeping the P.D. across it constant, by what factor does the drift speed of electrons change?

Resistance of conductor is doubled keeping the potential difference across it constant. The rate of generation of heat will :

Define drift velocity. A conductor of length L is connected to a dc source of emf E. If the length of conductor is tripled by stretching it, keeping E constant, explain how do the following factors would vary in the conductor ? (i) Drift speed of electrons (ii) Resistance and (iii) Resistivity

If the length of a potentiometer wire is increased by keeping constant potential difference across the wire, then

Keeping the potential difference constant, the resistance of a circuit is doubled. The current will becomes:
