About : I am a dad and conserve and love sharing what I am up to. My content is class friendly and fun !

Safety first When it comes to condom, it pays to double check your workplace and error on the side of caution. I can give some guidance on how to choose equipment condom for your application, but it doesn ’ metric ton entail it is safe for your person if you get in the center of your electric racing circuit. if you have concerns about doing this on your own particular stick out, ask for aid.

Some things to keep in judgment for safety : electric potential does not kill, current kills, but electric potential is required to push the current along. sol, while a 5 Volt 1 adenosine monophosphate power provision may be sanely dependable to work with, a 100 volt .1amp is potentially deadly if it ‘ bites ’ you in the wrong spot.

Batteries/power supplies have specific direction/polarity ( positive or negative ) that the moves the stream along. If you wire your circuit backwards, the current will attempt to flow backwards through your device and could damage it. Check the polarity of your batteries and might supply to ensure they match.
