Electro-static Discharge (ESD) Tutorial - cypress
Electro-static Discharge (ESD) Tutorial March 2012 3 Cypress Semiconductor Corp 1 What is ESD and how is it caused ? The charge at the surface of any material is generally neutral, ie neither positive nor negative, unless some energy is imparted to the surface causing an imbalance of electrons to occur
Common static electricity problems and remedies: a series ,
Static Electricity is the confinement of excess charge: When an excess of either positive or negative charge is confined into a relatively small volume (far from any excess charge of the opposite polarity) mutual repulsion occurs between the charges within that volume This repulsion causes the charges to try to leave the confining volume and .
Testing for Static Electricity | PBS LearningMedia
In this video segment adapted from ZOOM, cast members test for the presence of static electricity using a device called an electroscope Viewers learn that rubbing certain materials together causes electrical charges to build up on the surface of one of the objects and that charge moves easily through conductors but not through insulators This resource is part of the VITAL NY State Test Prep .
