Same applies to the sub ohm 0.7ohm and 0.4ohm coil start lower and move up gradually.
What is sub ohm vaping?
Sub-Ohm vaping when you build a coil that has a resistance of less than one ohm. The reason you might want to do this to increase the power output of a device that has a fixed voltage such as a mechanical mod or non-variable regulated device. This is really for advanced vapers who “Sub-Ohm” to create more flavor or vapor.
Why do I need Ohm’s Law?
Vaping safety starts with understanding the limitations of your battery. Now that mechanical mods, high wattage regulated mods, rebuildable dripping atomizers, and rebuildable tank atomizers are becoming increasingly popular, it’s in your interest to be safe. After all, you are putting a high voltage or high wattage battery into a metal tube putting it up to your mouth and hitting the fire button!
What does the letter V stand for in a formula?
All that you have to remember is what the letters stand for in the formula; the easiest is “V” and “R” but “I” is a little harder as it stands for intensité (intensity). Described by the French scientist André-Marie Ampère as “l’intensité du courant électrique.”. V is the Voltage of your battery in Volts.
How many amps does a 0.5 coil draw?
So having a 0.5Ω coil and a freshly charged battery at 4.2V, the result is 8.4 Amps of current draw. As your battery starts to drain the current will begin to decrease, which means when the battery reaches 3.6V with the same load, the current will have dropped to 7.2A (I=3.6/0.5)
What is the max voltage of a battery mod?
We know the battery is 20A, but we’ll use 19A to give us a 1A margin. We also know our battery has a max voltage of 4.2V on a single battery mod. So the calculation is as follows:
What is R in a coil?
R is the resistance of your your coil in Ohms. Now that you know the relationship between voltage, current, and resistance you can use the triangle to help build your coils to get the current and wattage you want.
What happens to the current when the resistance of a coil increases?
From using both our formulas, you can see that if the resistance of the coil increases, then it will let less current flow (calculating current formula), therefore, generating less power (calculating power formula).
How many amps does a 0.5 ohm coil pull?
So that 0.5-ohm coil with a fully charged battery at 4.2 volts will pull a maximum of 8.4 amps and deliver 35.3 watts. You can see that as the resistance of your coil increases, current and wattage will both drop.

How many amps can a 0.5 ohm battery draw?
As you can see, with your 0.5-ohm coil and a freshly charged battery at 4.2 volts, the resulting max current draw will be 8.4 amps. If your battery has a 10-amp limit, you are well below the cap. Don’t forget that using a dual mechanical mod in series configuration will double your amp draw per battery, and you will have to build coils with twice as high resistance to be safe. Also note that as the battery depletes, the current will also tail off. For example, when the battery reaches 3.7 volts with the same load, the current will drop to 7.4 amps (3.7 volts / 0.5 ohms)
What is the second Ohm's law?
The second Ohm’s Law formula that can be of use to us is calculating resistance. Let’s say that you have a battery with a 10-amp current limit and you want to determine the lowest coil resistance that you can safely run without exceeding the CDR of the battery.
How to solve for current I?
How did we arrive at that? Look at the triangle and you will see that to solve for current (I) you must divide voltage (V) by resistance (R).
Is Ohm's law magical?
There’s nothing mystical or magical about Ohm’s Law. It’s a few formulas, usually depicted inside of a triangle, and anyone can easily learn and use the formulas with any regular calculator.
Can a coil see battery voltage?
People will argue that the coil will never see that actual battery voltage due to voltage drop within the mod, but to be safe, ALWAYS use the full theoretical battery voltage (at full charge) in your calculations.
What is Ohm?
Inside the exterior of your vape device is a simple circuit. Ohm’s law is used to determine the strength of the three aspects present in a circuit, namely current, voltage and resistance. As your vape is a simple circuit, it will be possible to determine these variables.
What is Ohm? Continued
V: This is the symbol of the voltage. This is the force that makes the electric charges pass through the wire and then, in turn, form an electric current. Certain vapes have a setting where you can change the voltage, which will have an overall effect on the electrical current.
Why is it important?
As the device works as a result of an electric current, it’s important to understand the working of it. Furthermore, understanding Ohm’s law will aid you with vape safety. Batteries have different resistance levels, resulting in different power outputs.
