as im a complete newbie on everything here i would like to show my work(i dont even know if i should call this work)
so on this first image i would like to know if each battery has 1.5v am i gettin 9v? and the green string its positive one? or i should use the black and the red string on the side of those things?(im not using this batteries its just a test) also the batteries on the middle thing gets really hot ... it looks like only them are being used cuz the others dont change the temperature
i think its everything fine here...
this thing also gets really hot..i cant even touch...it should be like this?
