A low DC voltage is produced by the thermocouple when the two junctions are at different temperatures. This voltage is referred to as the thermoelectric voltage. This thermoelectric voltage is produced by the temperature gradient along the thermocouple wires.
Re: What's causes the electric shock type pain in a tooth Hi DM69. I'm not a dentist but I'm pretty sure its the erosion of your tooth exposing the pulp, I had the exact same feeling in my tooth before I had it extracted a month ago, so I feel your pain.
You can reduce or prevent shocks from a buildup of static electric charges by taking the proper steps. A shock from static electricity is not a true electric shock but rather the pain from a hot spark jumping to or from your finger or other parts of your body.However, getting an unexpected shock simply from touching some object is still a nuisance to many people.y taking the proper steps, you can reduce or prevent shocks from a buildup of static electric charges. Dry skin rubbing on clothes made of synthetic materials is the greatest cause static electric charges in your body.
