In electrosurgery, which element is responsible for destroying tissue and coagulating blood vessels?

Explanation:
Electrical current is delivering the energy that causes tissue destruction and vessel coagulation in electrosurgery. As the high-frequency current passes through tissue, the tissue’s resistance converts part of that energy into heat. This rapid heating denatures proteins, disrupts cell membranes, and coagulates small vessels, producing both cutting and hemostasis. The blade is just a cutting edge and does not generate the heat; cold spray is not involved in this process. So the energy carrier driving the effect is the electrical current, with the heat produced by tissue resistance being the actual mechanism that destroys tissue and seals vessels.
