The resistance value of the Coil?

The resistance of the coil largely determines the size and taste of the smoke.

 The pursuit of large smoke using low resistance coil, the pursuit of taste reproduction using high resistance coil.

In the case of the same length of the coil, the thicker the wire, the lower the resistance;

in the case of the same thickness of the wire, the shorter the wire,

the lower the resistance. In general, the coil resistance value in 0.2-1.0 belongs to the big smoke type, greater than 1.0 for the taste type.
