What electrode size is typically more comfortable for the patient?

Explanation:
A larger electrode is typically more comfortable because spreading the same total current over a bigger skin area lowers the current density at any one point. This reduces local heating, irritation, and sharp sensations, giving a gentler, more diffuse feel for the patient. Small electrodes concentrate current on a smaller area, which increases current density and can produce stronger local sensations or discomfort. So, using a bigger electrode generally feels more comfortable, though it may reduce precision in targeting very small areas.
