Video Transcript: What is Ohms and Sub Ohm Vaping | Vape School by ZampleBox
What are ohms and sub-ohm vaping?
If you're a vaper, there's a good chance you've come across topics like coil resistance and sub-ohm vaping. These topics can be a little challenging if you're new to vaping. In this video, we're going to discuss some of these things to help you understand them in a way that will improve your vaping experience. The areas we're going to be discussing are volts or electrical pressure, ohms or resistance, and amps, or currents. The amount of electrical pressure in your battery is measured in volts. When using your vaping device, electricity flows out of the battery and through the coil. The amount of electricity that's actually flowing through the coil is measured in amps. The more amps of electricity there are flowing through the coil, the faster the coil heats up. This is where ohms come in. Basically, ohms are how difficult it is for the amps of electricity to squeeze their way through the coil. The higher the ohms, the more resistance the electricity encounters when flowing through your coil. It helps to think of your coil as a straw and the electrical current as water.
If your coil is made up of a really thin piece of wire, then the electricity is going to encounter more resistance, that is, it's going to be harder for the electricity to flow through it. However, if your coil is made up of a thicker gauge of wire, then it will be easier for the electricity to flow through it. Also, the length of the wire in your coil affects the resistance as well. So, a coil made up of a really long piece of wire with a lot of wraps in it will make it harder for the electricity to flow through. Sub-ohm vaping refers to using a device with below one ohm of resistance. When your coil's resistance is below one ohm, this makes it possible for lots of electricity to flow through it and depending on the amount of volts in your device, it can produce more vapor.
The potential danger with having very low ohms is that if too many amps of electricity flow out of the battery too quickly, it can overdraw your battery, causing it to burst. Luckily, there are many regulated devices that have the necessary circuitry and fail-safes to prevent this from happening. So, if you have a coil on your device that has resistance that's too low, the device is prevented from turning on. Click here for some additional resources to make sure the batteries in your device are being used safely. If you're using devices that are unregulated, it's extremely important that you check the resistance of your coils before using them. There will be a video in the future discussing how to check resistance and safely build your own coils for unregulated devices. To summarize, volts measure the amount of electrical pressure in your battery. Amps measure the amount of electricity that actually flows out of your battery and ohms measure how difficult it is for that electricity to flow through your coil. The lower the ohms, the more easily the electricity can flow. We hope you found this information useful. Thanks for watching.
