Abstract
This invention provides a current detecting apparatus including three conductors disposed radially from a branch point such that they are branched, three hall devices disposed between conductors adjacent of the three conductors, and an operation processing circuit for detecting a current flowing through each of the three conductors based on an operation output obtained by a predetermined operation based on electric signals from the respective hall devices.
