The Science Behind E-Cigarettes

You might be considering making the switch from cigarettes to vaping, or trying out e-cigarettes because you’re friends all rave about how great it is. E-cigarettes have been in the spotlight a lot lately, so you probably already know a little bit about it, but you might not really understand how it works. If you’re a beginner and you’re planning on buying an e-cig device, then it’s a good idea to understand how they work, at least in a basic sense. It never hurts to know what you’re doing, and if you understand how your e-cig works, then you’ll have an easier time with resolving any issues that might pop up later.

Read on below to find out the science behind vaping and how it works.


How e-cigarettes work

There are a few different components that every e-cigarette will have. These include a mouthpiece or drip tip, a cartridge (sometimes called a tank), a battery (usually lithium ion and rechargeable) and an atomiser which heats your e-liquids.

Your atomiser will include a heating coil, which is powered by your battery. When your e-cigarette is turned on and in operation, the heating coil will warm up and heat your e-juice. Eventually your e-juice will get hot enough that it will begin to vaporise. This is when you can inhale and enjoy the vapour from your e-cig. Your e-liquid usually needs to reach a temperature of between 100 – 250 degrees before it will turn into vapour.

Your atomiser will have a wick on it, which is designed to absorb your e-liquid. This stops too much reaching the coil at once, and slows down the amount of vapour being produced for a steady supply of vapour. Oversaturated wicks can mean you need to refill your tank more regularly, or cause you to inhale droplets of e-liquid.


Resistance and Ohm laws

When you’re new to vaping, all the mention of watts, resistance and voltage can be confusing. It’s hard for vaper’s to determine what settings produce the best vapour clouds and the most enjoyable experience or what exactly the relationship is between all these elements. A basic understanding of ohms law and the principles and importance of electrical current resistance is important for newcomers. If it’s been a while since you were in a physics class then you should brush up on the basic principles.

The first thing to know is that an electric current is created when electrons move through a conductor. When these electrons collide with the atoms of the conductor, it becomes more difficult for them to move freely, this is called resistance.

Shorter, thinner wires have less resistance because there is less distance for the current to travel and less atoms to carry the electrons. Resistance is measured in ohms, higher ohms equals higher resistance. Low resistance vaping is known for creating bigger vapour clouds.


How do these principles work with e-cigarettes?

The greater the electrical resistance, the more heat that is produced because of the friction caused by the current travelling on the circuit. Your atomiser uses electrical resistance to warm up and heat your e-liquids. Wattage is the power behind your system, and an important indicator of the vapour that you e-cig will product because it pushes the current around your coil at a greater rate, increasing the heat produced by your coil.

The devices that will create the best vapour clouds are low resistance and high voltage. This isn’t always a great combination as it can burn e-liquids if not monitored carefully.

Vaping uses smart scientific principles to create the amazing vapour clouds that e-cigs have become known for.
