Hello, maybe this is the very EASY and ANYONE can EVEN determine the answer but since I am not belong to those, here I AM asking. First, If for example, I had 8 1.5 volts battery (AA) and I connected each others. So after I connected each others, I will have 12 volts, right? So, now, I had a 12 v halogen lamp (which is let's say 50 w), do those batteries can operate this halogen lamp well? As same as what what wet cells power gives. OR batteries have their own specification or whatever? OK, This one is very easy easy easy and I can even determine. But I'm just correcting myself. OK. Let's say here's the 8 1.5 (AA) batteries. - +- +- +- +- +- +- +- + Is the connecting batteries correct? I mean they are designed correctly? SO, if they were so, where is the pole/terminal of - and +? I means let's say my device had polarity so where should I put the negative and positive? Should I put the negative wire on the very very first sign (which is -) and the positive at the very very last sign (which is +)? THANKS A LOT FOR UNDERSTANDING MY QUESTIONS EVEN IT IS SO NONSENSE! HAVE A GREAT day!
