What term describes the instantaneous discharge of static electricity that has built up on a surface?

• A. ESD
• B. ESD Control Program
• C. Noise
• D. Conductive Wrist Strap

Answer: (A)

Electrostatic discharge is the instantaneous discharge of static electricity that has built up on a surface. When charges accumulate on a surface, they seek a path to balance potential; if a conductive path to ground or another surface appears, the stored energy releases suddenly, often as a spark. This term best fits the description because it refers specifically to the rapid release of accumulated static charge. The other options describe related concepts or tools, not the discharge event itself: an ESD Control Program is the overall efforts to manage and prevent ESD incidents, Noise is random electrical interference, and a Conductive Wrist Strap is a tool used to prevent ESD by keeping the operator at ground, not the discharge.
