ESD, or Electrostatic Discharge, is a sudden and unexpected flow of electricity between two objects with different levels of static charge. This phenomenon can occur when two objects come into contact or are separated, causing a spark or shock that can damage electronic components and devices. ESD is a common occurrence in our daily lives, but it can have serious consequences in industries such as manufacturing and electronics. To prevent ESD, proper grounding and protective measures must be taken to dissipate static electricity and protect sensitive equipment.
