The interface-current ii and the eloctroosmotic velocity vosn, have been measured in a specially designed doughnut channel with dilute aqueous solution of NaCl. The measured relation between ii and vosni was compared with the theoretical one based on the diffuse double layer model which predicts a linear relation between the two. When the applied external electric field is not so intense, the measuredvosmrelations coincide quantitatively with the theoretical one. Under high electric field, however, the experimental results deviate from the theoretical linear relation. This deviation is due to the temperature rise of the solution in EDL caused by Joule heating of the interface current.
