voltage dropout

[herbsman05]

i made a volt meter that you can attach to pv's (just like the one from madvapes and COV) and whenever i attach an atty to the volt meter the voltage drops. is that normal? what actually happens when you attach an atty to a pv? does the atty act like a resistor?

e.g.

im using a 2.3ohm atty

w/o atty - 4.2v

w/ atty - 3.4v

thanks!!!

Yes - atty acts like a resistor to electrical power. That is why they are rated in ohms, just like resistors and why we call them standard resistance, low resistance, etc. The voltage that disappears is making heat.

And what is the battery? You cannot measure Ego with a voltmeter - only with an oscilloscope. Ego's voltage switches very quickly between 3.6 and 3.2v to make an average of 3.4v. Attempting to measure an Ego with a voltmeter can also sometimes make the battery malfunction for a while.

thanks dormouse!!!

does all pv's/mods do that? how about vv? i remembered i saw a fellow vaper that made a vv using the kit from madvapes and he set the vv mod to 3.9v and when he vaped the voltage stayed the same on the lcd, how come that didnt show the any voltage drop?

A regulated VV keeps its voltage at what you set. However, if his voltage was 3.9 w/ an atomizer on then then he either had it set higher than 3.9v or whatever he was using was measuring before the atty.

And note - re your 4.2 - in case you are, you don't measure batteries right off the charger. All real 3.7v batteries are up to 4.2 fresh off the charger - that does not make them 4.2v batteries. There is a a steep voltage drop shortly after you start using the charge and then the voltage stick to its slowly declining plateau with a steep dropoff at the end near the end of its charge. Only regulated and switching regulated devices hold the voltage more level (and with those you may not get that nice extra heat at the start)

If you get a PV with boost circuit technology you will have no drop off in power and if it's a variable wattage model, then you will have the best of all possible options.

he set the vv to 3.9v w/o the atomizer and when he vaped the display still stayed at 3.9v. that really confused me because there was no drop of the voltage even if there is an atomizer in the circuit? how can that be? can it be that the lcd is just wired to show the regulated output voltage of the battery but not the actual voltage of the circuit w/ and w/o load?

what do you mean "best of all possible options"?

You will have the best in flexibility and the best in consistency. It provides consistent power at whatever level you set it at and the flexibility to changes your settings to fit the atty or carto or eliquid you are using at a particular time. There are even models that automatically adjust the power output to compensate for the change in the resistence of the atty/carto as it is used.
