Making sounds with a piezo
Making sounds with a piezo

... 'Piezo' normally refers to an electrical component which can be used to make sound, however more broadly a piezo is a component that is susceptible to the two-way piezoelectric effect where pressing or squeezing the piezo element can create a small voltage, and vice versa a small voltage can create ...

... transmitted at a 0-10 volt or 4-20 milliamp level, signals from load or force sensors are typically one thousand times smaller, or 0-0.010 volts. A ten pound change on a 100,000 pound scale would correspond to a signal change of 0.000001 volts (1 micro volt). Therefore, cabling must protect against ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
