    More or less resistance

    Ok, I've spend over an hour searching so I'm going to ask a noob question.

    Does more turns on a coil equal greater or lesser resistance? All my EVOD coils seem to have 5 turns and come in at around 2 ohms. I built a couple with 4 turns and they're the same. Should the turns have a gap between them or should they be snugged up against each other?

    Ok......two noob questions....

    More turns, more resistance (with the same wire wrapped around the same diameter "mandrel")

    I believe more wraps = higher resistance
    And gap or no gap, either works (i think)
    Also thinner wire = higher resistance

    Snugged together becomes a contact coil. In my Evod (or ProTank or ...) coils, 9 wraps around a 2mm drill bit using 30AWG Nichrome (wrapped as a contact coil) gives 1.7 ohms.

    Resistance wire can be measured by ohms/m. The longer it is the more resistance. More turns more resistance. Greater diameter of turns more resistance. The thinner the gauge more resistance.

    Look here for something to play with. It's unfinished and is off by 30% but will give you an idea of what is going on.

    Or PV Web Apps (scroll down a bit)

    Would be great if it worked. Used 3 different browsers and it only allows one calculation. After that you have to refresh page and start again. I HATE IT because I want to use it.
    EDIT> scratch that. Working in chrome
