I have an exam coming and my question is :
Why do we sometimes have a tiny electical current ( spark ) when we take our sweater off because of the shirt and jacket rubbing each other , the negative charges will have static electricity
But for an electrical current , it needs and complete circuit and needs a battery , how does the spark happen if there was no battery or a complete circuit ?
Since this is not my area of expertise, I searched Google under the key words "static electricity" to get these possible sources:
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
