Which type of current is primarily used to achieve electrocoagulation?

High frequency current is primarily used to achieve electrocoagulation because it allows for efficient thermal effects without causing extensive damage to surrounding tissues. The high frequency creates a rapid oscillation of electrical energy, which generates heat in the targeted area. This heat effectively coagulates protein and cellular structures, leading to desired results in treatments.

Using high frequency current facilitates a more controlled and localized treatment, making it particularly useful in electrology for removing hair or performing skin treatments. It minimizes the risk of damaging adjacent tissues and promotes a quicker healing process. This is critical in electrocoagulation, where precision and efficiency are paramount to achieving desired therapeutic outcomes.
