    Ohm's law for beginners (or the amp-hour fallacy)

    Thank you Cobra, and a special thanks to Evan for providing an equasion. The next time I measure a 30 inch door, I will plug that into your equasion: Feet = inches x 12 Feet = 30 x 12 Feet = 360 (Ring....Ring...) Hello. I need a 360 foot door.
