Question

Define the term 'drift velocity' of charge carriers in a conductor and write its relationship with the current flowing through it.

Answer 1

In a conductor there are charge carriers called electrons or ions.when a potential difference is applied the electrons move from lower potential to higher potential.

at any temperature T at which the conductor is kept the moving electrons find vibrating atoms in its path as well as other electrons and ions.

so it moves in a jig jag path and slowly it reaches the other end.
