Just proof that there's no dumb questions...

Especially compared to some of the ones I come up with!

My GPS operates on 3 VDC. My cell phone charges at 6 VDC. My truck obviously supplies 12 VDC to the "cigarette lighter".

Without some complicated inverter/transformer/rectifier setup, how does one reduce the DC voltage? Resistors?

I should mention that this is a curiousity Q, both my GPS and cell phone work just fine plugged in as is!

I just don't know how it works!
