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

Two wire A & B are of the same metal and are of same length have area of cross section in the ratio of 2:1 If the same potential difference is applied across each wire. What will be the ratio of the current flowing through the wires A & B ?

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?

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 )

Two different wires X and Y of same diameter but different materials are joined in series across a battery. If the number density of electrons in X is twice that in Y, find the ratio of drift velocity of electrons in the two wires .

A wire with an area of cross-section as 1 mm2 has a resistance of 10Q, when a potential difference across its ends is 8V. Calculate the drift velocity of electrons. Given,number density of electrons in wire as 8 xx 10^20 electrons per cubic meter.
