What are coils and how do they work?
What is a vape coil?
Vape coils are one of the most necessary elements in any vape device. Coils are responsible for heating up the e-liquid and producing vapor from it. The coil is essentially a wire (made from Kanthal, Titanium, Stainless Steel, Ceramic, and more!) that is wrapped in a spiral shape around your device's wicking material (usually Cotton).
How does a vape coil work?
When you're vaping, you want the wick to be saturated in e-liquid. When the battery is engaged, it starts to heat up the coil, the coil will then vaporize the e-liquid into vapor. The vapor will travels up through the airflow chamber (Engine Room/Clearomizer), as it is frequently referred to, and there you have vapor ready to inhale. The coil wiring is made from conductive, heat resisting materials, most likely stainless steel but other materials are commonly used as well.
Skillful and knowledgeable vapers who use mod kits for sub-ohm vaping will often make their own DIY coil setups using an RDA. They purchase special wires and their preferred wick material and then spend time tightly winding the coil wire, manually fitting it into their vape kit, and then pulling the wicking material through the middle of the coil. Most vapers purchase pre-built replacement coils for Tanks and Pods which looks like a little metal piece with the coil in the middle and the wick wrapped around it.
What does Ohms, Voltage, and Wattage mean and how do they effect vaping?
ohm: Pronounced /ōm/ Noun. The unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
Ohm's Law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit. In other words by doubling the voltage across a circuit the current will also double. The lesser the resistance (ohms), the larger the amount of current passes your coil creating more vapor and a larger puff. If you raise resistance, the coil receives less current producing less vapor and a tinier puff.
Voltage: Measurement of energy contained within an energy field/electric circuit at a given point. The greater the voltage, the higher the temperature, meaning more vapor will be produced from a high voltage device or coil.
Wattage: A measure of electrical power expressed in watts. It is used to quantify the rate of energy transfer. The watt is named after James Watt, an 18th-century Scottish inventor. A higher wattage means your coils will heat up faster, and produce more vapor than if you used a lower wattage. Lower wattage is preferred by those who use a higher nicotine or salt nicotine e-liquids or those who don't like taking huge puffs.
