The potential difference across a given copper wire is increased. What happens to the drift velcoity of the charge carriers?

If p.d. V applied across a conductor is increased to 2V, how will the drift velocity of the electron change?

If potential difference across resistor is increased, will the current increase or decrease?

The following table gives the length of three copper wires, their diameters and the applied potential difference across their ends. Arrange the wires in increasing order according to the following The magnitude of the electric field within them?

The following table gives the length of three copper wires, their diameters and the applied potential difference across their ends. Arrange the wires in increasing order according to the following The current density within them.

A wire with an area of cross-section as 10 mm^2 has a resistance of 5Omega , when a potential difference across its ends is 25V. Calculate the drift velocity of electrons. Given the number density of electrons as 5 xx 10^20 electrons per cubic meter ( e//m^-3 )
