I only realised when you quoted it that I said staple-fused rather than staggered fused, my apologies. I'm going to blame that on the sunshine, moonlight, good times and the boogie...
To elaborate on why staggered claptons ramp up faster - the outer wire has very little influence on the overall resistance as electricity travels via the easiest path. Making staggered coils means there's more space between the wraps of the outer wire and thus less wire overall for the same length of finished wire. Therefore the finished wire would have less mass and the same resistance. I personally can't tell the difference in flavour on a regulated device but on a mechanical mod the difference in ramp up does seem to influence the flavour.
Thank you. I understand that current will take the path of least resistance but that is not what I was inquiring about.
Now bare with me, it’s early and I do sometimes get confused over the many different types of coils – alien’s, juggernauts, fused, stapled etc. But a Clapton coil by definition is a single lower gauge core with a single higher gauge wrap. What these gauge’s are is up to the designer of the coil and are not bound to any specifics.
My understanding is that a Staggered Fused Clapton is essentially 2 cores of lower gauge wire that are wrapped each in a staggered fashion with a higher gauge. They are then fused in parallel with another higher gauge wrap that is also staggered.
You claim this type of wire should be of a similar resistance as the same Clapton coil but with a lower mass. This I do not understand. Within the limitations of a vaping coil should we use the same metal, say Kanthal, and the same dimensions of coil, say 3mm ID with 5 wraps, you will never achieve the same resistance between the 2 types of coils…it’s impossible. Should we use the same gauge, say 26 awg for the cores and 36 awg for the wraps, plus same coil dimensions of 3mm ID and 5 wraps, the Staggered Fused coil will always be of lower resistance and of higher mass.
Ramp up time is dependent on the Specific Heat Capacity of the metal used, the mass of the metal and the resistance of the metal. If using the same metal, again say Kanthal, then the Specific Heat Capacity will remain the same. However, changing the mass will always change the resistance to which both will affect the ramp up time.
When dealing with complex coils, such as a Staggered Fused Clapton there is no easy equation that states it will always ramp up quicker than just a regular Clapton of the same dimensions. I am open to the fact that one could design a Staggered Fused Clapton that performs in such a manor by using specific gauges, but that would require some extreme attention to the design.
