ohm's law for dummies

[Whipple]

Ive googled about 5 or 6 different explanations on ohm's law and it hasn't clicked.

Can someone please try to explain it to this dummie?

Do any of these links help you?

It's not as hard as a lot of the "explanations" make it sound. There are a few simple fractions basically to find watts, ohms, voltage, and amperage when you know the other variables.

A hydraulic analogy:
Resistance (ohms) - diameter of a pipe.
Current (I) - how much water you can get from a pipe in one second, i.e water flow.
Voltage (V) - what pressure you apply to move water through pipe.

Smaller diameter of a pipe (higher resistance), more pressure (voltage) you should apply to get the same water flow (current).

+1 to @Alien Traveler. Use the Ohms Law Calculator, linked above, to help. You know your atomizer resistance (or should, if you bought a meter) and full charge on an IMR battery is appx 4.2 volts. Plug those two into the appropriate lines, hit calculate, and it will tell you the amp draw and watts. Just check and make sure the amp draw is no more than 80% of your battery's safe amp loading and you should be fine. If you're shooting for a specific wattage, plug in 4.2 volts and the watts you want, and it will tell you where to build your coil and the amps to check for safety. All that said, it really is better to study it until you understand it

Im not planning on building anything until I can completely understand it, so no worries.
