Designing Electronic Systems for EMC: Grounding for the Control of EMI
There are two primary reasons for grounding devices, cables, equipment, and systems. The first reason is to prevent shock and fire hazards in the event that an equipment frame or housing develops a high voltage due to lightning or an accidental breakdown of wiring or components. The second reason is to reduce EMI effects resulting from electromagnetic fields, common impedance, … [Read more...]

MYTH: Did Ben Franklin Really Discover Electricity with a Kite and a Key?
The American legend likely sprang from an article Franklin wrote for the Pennsylvania Gazette in 1752 describing a theoretical kite-lightning experiment. Supposedly, the genius of yore picked a stormy day to fly a silken kite, complete with a lightning rod and a key dangling on the end of the string. When the lightning struck the kite, the powerful bolt travelled down the … [Read more...]
