    Electric Spark
AI Thread Summary
Electric sparks felt between people or objects can be attributed to static electricity, which is influenced by environmental conditions. In hot, dry climates, such as the one mentioned with 15% humidity, static charge buildup is more pronounced due to reduced moisture in the air. The type of flooring, particularly carpets made from wool or synthetic fibers, can also contribute to increased static electricity. Seasonal variations in humidity are significant factors, often more so than temperature alone. Understanding these elements can help explain why electric discharges occur more frequently in certain environments.

TL;DR Summary
Why an electric spark is happening a lot and much stronger in a new country I recently moved to
Hello All!

You know sometimes you touch another person and you felt an electric spark between both of you, or sometimes with things like the door handle, etc. I moved lately to a hot and dry country where the temperature is around 40-45 Celcius degrees now in August, but since I moved here this electric spark happened a lot and much stronger. Yes, I know maybe I must plug myself into a battery to charge it for free Huh, but really why this is happening and is the reason related to the higher temperature?

Dry air slows down the charge loss, so it is easier to build up large voltages. But, often the culprit is just the surface on which you are walking - some carpets/floor types have tendency to quickly built static charges when you walk on them, it doesn't have anything with geography. Back in early nineties I worked at a company where we were forced into replacing the carpet after we lost some hardware to static charges (and I don't speak about anything really fancy, we killed interfaces between things like printers, computers etc).

Are the floors covered with the same material as before ?
Do you wear the same shoes as before ?
I would expect seasonal variation in humidity to be more important than temperature.
What are the two countries ?
 
@Borek @Baluncore
I think you both are right. My current country is so dry [15% Humidity], while my old one was humid. Therefore the electric discharge is easlily happening!
But thank you for mentioning the idea of "some carpets/floor types", I didn't know of that before... what types do you mean[have a tendency to quickly built static charges]
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
