I recently found out that if you have resistors of the same value wired in paralell, the resistance is lower than one of the resistors in the paralell. For example, if you have 2 resistors that are 50 ohms each, wire them in paralell and their resistance is 25 ohms each. I don't understand...
What fume extractor would be the best for extracting solder flux fumes (any recommended models)? I use solder that contains Tin and silver with no lead so I dont need to worry about lead.
Is rosin flux a carcinogen? Its a rather simple question but I have been looking for info on it on google but I can't find anything that consults my question directly.
Thanks
