Thanks for laying it out in simple terms, also thanks for bringing to everyone's attention about ohm's law calculators for smartphones. Keep 'em coming!
Why do Any of that when you can just look at the wattage chart based on voltage and ohms. Google wattage.png & imageshack to find a nice chart. All the math for 1.4 ohms up to 5.5 and 3.0 volts up to 8 volts is done for you. Only reason to do the math manually is to check your setup if you think it's not performing correctly. Could tell you of manufacturer's defects. Can you Please explain to us all the reasons why you need to do these calculations? Without that, your video makes no sense to me.
Not even worth discussing. The only way to figure out the watts consumed/dissipated you are vaping at is do a voltage test, with the atty 'under load'.
A 10440 and an 18650 will both read 4.2V off the charger, yet with the same atty the 18650 will produce over 20% more watts. The spread is even greater if a 1.5Ω atty and an IMR18650 is used.
@TheGusK ok. Explain to everyone here EXACTLY how 4.2 volts on the same ohm load will produce more wattage. PLEASE explain to everyone here EXACTLY how Ohm's law ceases to apply in the world of rechargeable batteries. Please come up with a rational explanation as to how an atomizer is "under load" when the atomizer IS the load. Seriously, man, you have NO IDEA what you're talking about and you're confusing the issue so until you KNOW ohms law don't bother.
@TheGusK Now...To clarify...(look up the words in CAPS) we determine AMPS by calculating VOLTS (output) divided by RESISTANCE (in ohms). The atomiser is the RESISTOR. So 4.2 volts (from the poles of the e-cig) divided by 1.5 ohms (from the atomizer) equals 2.8 AMPS of CURRENT. 4.2 volts times 2.8 amps equals 11.76 WATTS. Again, this is incontrovertible FACT (yes, look that one up too) as defined by Ohm's law.
Not all meters 'zero' when testing ohms. You need to to just touch the probes together, first, and see if you get a reading. Mine shows .3Ω, which has to be subtracted..
Your unloaded voltage of 4.23V is meaningless, nobody vapes at 4.23V with a battery. The voltage needs to be determined with the atty under load, to determine the actual vaping voltage and watts. And this voltage will vary depending on the ohms of the atty.
In your first example you are probably at 3.6V with 2.6A = 9.25W
@TheGusK you're so off base I shouldn't even bother to reply but I will say this. It's clear that your understanding of Ohm's law is a little off. Please do more reading (and maybe even study electrical theory in-depth) and you'll see how wrong you are. ANYONE who uses rechargeable LiOn batteries has a period where 3.7 volts is exceeded. 3.7 volts is the RATED max. Current (time/space) output voltage/resistance=amps. Output voltage x amps = watts. This is an incontrovertible fact.
uuuuugggggg you didnt use a true rms so your voltage reading was really an average youll have to recalculate haha just bustin your nuts i laffed my ass off watching u keep it up Terra Nader.....willie
for the one's who have an iphone/ipad: for free the app Ohm's Law, works perfect, simple and to the point, no need to understand anything, just enter whatever you want to get.
@emonty999 Absolutely. There are free ohm's law calculators all over the place for all different platforms. If you don't want to do the math manually, scoop one up. Instant answers :)
@so0o0confused The wattage will vary depending on the voltage. We use devices which range from approximately 3.7 volts up to nearly 13 volts. Common voltages are 3.7, 5, and 6 with some devices having controls which allow the user to change the voltage at will. Knowing Ohm's law allows us to select the right voltage for what we're trying to accomplish. It's complicated but it really does help.
