What are ohms?

Coil resistance is measured in “ohms” which essentially indicates how quickly electricity is able to travel through something. In short, the lower the coil resistance, the easier it is for electricity from your battery to travel through the coil. How does the coil resistance affect my e-cigarette? Essentially, the lower the coil resistance the quicker the coil will heat up, creating more vapour and typically a warmer hit. A higher coil resistance will take longer for the coil to heat up, producing less vapour and typically a cooler hit.
