In Pulsed DC is current in a single direction only.
In AC current flow actually reverses in the circuit.
Pulsed current would be if If I simply fired my button on my atomizer multiple times a second. (on...off...on...off...on...off)
AC would be as if I took my battery and reversed it multiple times a second. +/-... -/+...+/-...-/+...+/-...-/+
A hertz is a simply a cycle per second, a cycle can mean pulse DC or AC.
33 hertz for a pulsed DC signal means that the circuit goes from on to off to on again 33 times a second
33 hertz for an AC signal means that the current goes in one direction, reverses direction, then reverses to it's original direction again 33 times a second.
I can put safely put a 1 Farad capacitor on a pulsed DC load. However if I put a 1 Farad capacitor on an AC load I'd better take cover.
You are still going to have a collapsing magnetic field being induced into the coil. The voltage changing polarity doesn't really matter.

...none of which matters. The reactance is on the order of micro-Ohms.
The E-Vic fires at 104.9 Khz so it should be on the list of non-rattling devices....

I understand what you're getting at.. if you weren't arguing that RMS-DC was AC, I'd agree with you... but are you saying an electromagnetic field isn't different between AC and DC?..Originally Posted by Friscoweather:11689722
And it'd probably be best not to start an argument with "sorry, but you're wrong," especially when you're wrong.
Sorry....but you are all wrong... (Just joking). But seriously, electromagnetic fields and inductance in the coil is not what makes the difference. It's heat.
Heat generated at the coil. Joules. That's what cooks juice. There's another post here that I think lays it out pretty point blank. It explains why higher frequency devices taste "smoother" and it also explains why this effect is more pronounced in stacked battery configs on 33hz chipsets due to the higher amplitude PWM signal.
Also keep in mind, while the ProVari does have 800hz PWM, it is also filtered BEFORE it hits the coil, this is why it does not show up on a scope and why you can put a DC volt meter on it and get a reading. The same holds true for an MVP2 or VV3 (frequency may be different, but it too is filtered to straight DC). A 33hz device is non-filtered, which is why you get no reading on a DC volt meter.
Provari on an Oscope vs Vamo
A coil does not discriminate between DC and pulsed AC. It does not care what the minimum voltage and the maximum voltage is, or what side of "zero" they are. (Remember, ground is relative.)
What the coil cares about, is the difference between max and min voltage, and the frequency. (And probably the waveform to some degree.)
Still, unless someone can make a convincing argument that the inductance of an atomizer coil is of any significant magnitude, the point is moot.
