Hello vapers, today we will discuss about one of the main topics and must know for everyone that start vaping – the Ohm’s Law and how to vape safely.
Why do we need to know about Ohm’s Law?
We often see photos of exploded electronic cigarettes, burning pant, burns, etc.
What do we need to know?
First of all, let’s talk about our batteries and what we must know about them:
Unit of measurement (symbol V) of the electric potential and of the electromotive force in the International System. In other words, it is the unit of measurement of the electric voltage.
The watt (symbol: W) is the unit of measures of the power in the International System.
One watt equals 1 joule per second (1 J / s) and is equivalent, in electrical units, to one volts multiplied by amperes (1 V × A).
That is unit of measurement of the intensity of the electric current.
Simply our battery autonomy.
The Ohm’s Law
In physics, the law of Ohm, whose name is due to the German physicist Georg Simon Ohm, expresses the constitutive law of direct proportionality between the difference in electrical potential applied to the heads of a conductor and the intensity of the electric current that passes through it. The proportionality constant is called electrical resistance.
Another relationship, also called improperly the second law of Ohm, allows to calculate the resistance of a material starting from resistivity, length and section.
Denoting with V the difference in electrical potential at the ends of an electrical conductor and with A the intensity of electric current passing through it, the Ohm’s law has the form:
And R is the resistance characteristic of the conductor. It is a constant independent from the entity of the current. With this formula we can find others:
I ATTACHED THE OHM’S WHEEL WITH ALL THE FORMULAS:
The formulas that we need most are those:
W= V2/R A=W/V
Knowing those equations we can determine what resistance we can use with our batteries.
Once we found the max watt produced with a certain resistance we can calculate the Ampere that we would ask from our battery, if they will be higher than the continuous Ampere released by it we will have to change resistance with a bigger one. If they are lower we can use them.
The Mooch Table
To be even safer I recommend you to use the Mooch tests to check how many ampere can release a specific batteries as often the data released by the manufacturers aren’t correct.
If you search online the Mooch’s test of your battery you will surely find it on his Facebook page.
And for the lazy guys?
For the lazy the web comes in clutch by giving us sites that allow you to do all these calculations automatically.
This Site is also my favorite site.
You have to set the Voltage and Amperage of your battery and automatically it will give you the remaining settings.
KEEP ON VAPING BUT REMEMBER DO IT SAFELY!
