Quizplus · Accepted Answer

The patient return electrode is responsible for delivering alternating current back from exposed tissue to the ESU generator. It is placed on the patient's skin at a location remote from the surgical site and provides a low-resistance path for the current to return to the generator. The active electrode pencil delivers the high frequency current to the surgical site, the foot control pedal regulates the amount of energy delivered, and the third prong of the grounded plug provides an electrical ground for the circuit.
