Results are presented for an experimental study of the temperature dependence of the excess current Iexc(T) in superconducting thin-film microbridges of variable width over a broad range of temperatures and electric field strengths. It is shown that the behavior of Iexc(T) depends greatly on the voltage at which the excess current is measured.
