Write the mathematical relation between mobility and drift velocity of charge carriers in a coductor. Name the mobile charge carriers responsible for conduction of electric current in (a) an electrolyte (b) an ionised gas.

Answer» Mobility, `mu = ("drift velocity")/("electric field") = v_(d)/E`
(a) The charge carriers in an electrolyte are positive and negative ions. (b) The charge carriers in an ionised gas are electrons and positively charged ions.
