general electronics questions

Postby Donnieclark » Sat Nov 25, 2017 6:47 am


I have some questions about batteries etc. Firstly it possible to take 2 12V battery and take 24v and 12v simultaneously?? I've tried it and it didn't work I had to use another 12v battery to get the separate 12v. Why is this so?? And why do different circuits which work together in a machine must have their grounds common??? And what is the proper way to solder without getting too big/thick solds??? And lastly is there any alternative to using Mosfet for PWM?? From my experience Mosfet get burned often.


I didn't find the right solution from the Internet.
