Ohm resistance is pretty much a personal preference. LR will give a warmer vape, SR will give a slightly cooler vape. LR
coils are primarily used with fixed voltage batteries (ie mechanical mods).
Low resistance
coils actually use
more power from the battery. LR means there is more energy (amperage) being pulled from the battery (less electrical resistance...get it?). You do use more
voltage with a standard resistance coil, but it will be less power drain (amperage) than LR. That's Ohm's Law.
LR coils burn hotter and will heat up faster. SR coils will be less hot.
I use 2.5 - 3.0 ohm on my MVP and Provari's. You'll get a wider range of useable voltages with a standard resistance coil than lower resistance, as shown by the Safe Vaping Power Chart. I also prefer more of a cooler vape, hense the standard resistance cartos.
To help myself understand LR & SR coils, I imagine the following scenario:
A roomful of people (representing
electrons) are in a room (representing a battery or
power source). The room has two doors, one is wider (
low resistance) and one is narrower (
high resistance). A fire alarm sounds, so those people need to find the least restrictive way out of the room.
More people (electrons, or electrical energy) can leave the room via the wider door (LR) than can through the narrow door (SR) because there will be less resistance through the larger door. Electricity is the movement of electrons across the surface of an electrical wire. The amount of electrical energy (
amperage) pulled from the LR coils will be greater and a bigger drain on the battery because there is less restriction to the electron's movement.
