An electrical circuit is a closed current pathway along which electricity flows. Any current flowing in a direction or a path other than the intended one may lead to undesired outcomes, such as alternate site burns or shocks.
The type of circuit used in electrosurgery is termed a dipole circuit. A dipole circuit consists of two electrodes in contact with a dielectric or substance with limited electrical conductivity. In electrosurgery, human tissue is the dielectric. Diathermic heating occurs from electrical losses (transformation of the electrical energy into heat), which occur in the dielectric (tissue) located between the two electrodes. Two types of dipole circuits are possible: bipolar and unipolar.
