In a monopolar arrangement, how many larger dispersal electrodes are used?

In a monopolar arrangement, there is typically one larger dispersal electrode used in conjunction with a smaller active electrode. The purpose of the larger dispersal electrode is to evenly distribute the electrical current over a larger area of the body, which helps to prevent excessive stimulation and minimizes the risk of discomfort or injury. By using this configuration, the active electrode focuses the stimulating current on a specific area, while the dispersal electrode serves to complete the circuit and balance the current flow. This setup is particularly useful in various therapeutic applications where a concentrated effect is needed without overwhelming the surrounding tissues.
