Resistance reading error: how to behave when it happens
If you have found a reading error in your coil and you don’t know how to fix it, know that you are in the right place.
In fact, ignoring the causes of this phenomenon could seriously compromise the operation of your electronic cigarette, risking, among other things, burning the resistance.
That is why in this article we will see what to do when you read a value expressed in ohms that is different from what it should be.
Do you already have the impression that this article is for you?
Let’s start!
Coil reading: when to worry
In the UK, the term ‘coil’ is used as a synonym for resistance, although, to be precise, it only indicates the coil of metal wire that, together with the cotton, constitutes the resistance itself.
In fact, the literal translation of coil is coil.
But let’s get to the point.
The resistance of the electronic cigarette is expressed in ohms: in fact, the application of the first- or second-Ohm’s law makes it possible to take full advantage of the device, especially when it comes to electronic components.
Thanks to these laws it is possible to know the amount of energy present in the resistance (measured in Amps), the voltage applied to the coil and the value of the resistance expressed, precisely, in ohms.
In this sense, vapers can opt for devices with a low resistance according to their tastes: it is no coincidence that we talk about sub ohm vaping when this value is less than one.
As we have explained in detail in this article, the higher the value expressed in ohms, the less vapor is produced, simply because less power is supplied. This is possible by adjusting the air holes of the atomizer, which allow a certain amount of air to pass through according to the preferences of its owner.
Incorrect ohm value: the risks and consequences for your e-cig
But the crux of the question is: what if you know you have resistors, say 1.5 ohms, but the e-cigarette box says a different value?
We try to clarify this.
If the difference between the two is small (for example, 1.6 instead of 1.5), then there is nothing to worry about: in fact, it is physiological that slight oscillations occur during use.
But if the difference is too much (for example 1.0 instead of 1.5), then it is preferable to try to fix the problem before using the e-cig.
Why?
Note that the box delivers power based on the number of ohms it senses: if it senses too many compared to normal, it will deliver little power and the e-cig will have a tough time vaping the liquid.
Otherwise, it will be over-delivered, and you risk burning energy quickly.
In short, quite a mess.
What are the potential causes of these read errors?
As we have said, it is quite common for there to be a slight fluctuation in this value during vaping, so one should not be too alarmed.
But if the difference is substantial, then you should take steps to avoid damaging your e-cigarette.
Ok, but what are the causes of this phenomenon?
In general, we can summarize them in two main ones.
In most cases this read error is attributed to a box malfunction: if so, simply replace this component with a new one and you will have solved the problem.
However, there are other cases where the problem could be caused by the resistor itself.
That’s right, you read that right.
If you opted for a regenerative device, it’s likely that you (or whoever made it) made a mistake building it; if, on the other hand, your resistance is not regenerable, it may be defective.
As in the case of the box, it is enough to replace the old resistor with a new one and check that the problem does not recur.

Conclusions
In this article, we have tried to explain why your e-cigarette may have given an ohm’s resistance reading error.
As you may have read, a slightly higher or lower value should not be a cause for concern; If not, you need to make sure there are no case or resistor issues with your device.
By acting promptly, you will avoid burning the resistance or ‘fatiguing’ the e-cig while vaping.
