12v down to 9v

haha yeah good point Mad Scientists completely disregarded that he was gonna hook something up to it...oops :-PMoney is just paper

Power is fleeting

But your word is everything,

If your word means nothing,

You are nothing...think about it

I don;t think he meant that a voltage divider is unusable. He was only letting us know that a voltage divider is not as efficient, especially in the case of cars where you have an alternator,the input voltage varies too much thereby rendering the voltage divider idea not the most efficient or useful. When it is done with a more stable input, i.e, maximising the reduction in the number of variables would generate a more stable output. A lot of devices need stability.

Why can;t I edit my post? I think I have more than 50 points. I saw some spelling errors I would like to correct but cant so here I apoligize for my spelling errors. I think I spelled maximizing wrong. and I meant to put ' insstead of ;. Thanks.
