The purpose of this study was to examine pre-teachers' conceptual understanding of electricity. Tofulfill the purpose of this study, 24 pre-service teachers were requested to solve some problems aboutelectric circuit and electrostatic force. The results were as follows: Pre-service teachers solved well theelectric circuit problems, but they had difficulties in incomplete circuit. In the electrostatic problem,some pre-service teachers had difficulties in solving the relation between electrostatic force and tensionor gravity. And some pre-service teachers did not consider action and reaction.
