Ohm’s Law is one of the biggest
things that vapers need to know, whether your sub-ohming or just doing some
normal vape sessions. Not only will you be able to have a better vaping
experience, but you will also know how to make sure your devices are exactly
how you want them to be without damaging them. You will also be able to stay
safe since you will know exactly what your device can handle. Once we talk
about Ohm’s Law, hopefully you will have a better understanding.
Ohm’s Law refers to the basic relationships that are found in electrical
currents. For a given resistance, current is fixed to voltage. What that means
is when you increase the voltage in a device where the resistance is fixed or
constant, then the current goes up and if you decrease the voltage then the
current goes down.
With this law, there’s a certain way to calculate it.
The formula for that is: V=IxR or I=V/R
“V” stands for
voltage in volts.
“I” stands for
current in amperes
“R” stands for
resistance in ohms.
With vaping, you can use this
formula to make sure your coil builds are within the safe limits that your
battery can handle. The way you would calculate would be like this. Say your
charged battery has 3.7V and your coil is 0.5Ω. Since you have these, you can
now calculate the amps. Your calculation would look like this: I=3.7V/0.5Ω.
This would mean that I=7.4A. This means that, if your fully charged battery is
3.7V and your coil is 0.5Ω, if your battery limit is above 7.4A then you’re
good. One thing to point out is that when your battery starts losing charge,
your numbers will go down. Remember, if you have 2 of the 3 variables, you will
be able to use the calculation and get your answer.
Since we know how to calculate it, we need to discuss why it is important to
know what it is and how to use it. The biggest reason is so you can add on the
right equipment. You don’t want to just go adding on equipment without knowing
what your battery can handle. This can lead to all kinds of other issues.
One of the biggest reasons for this
is, if you get equipment that your battery can’t handle, there’s a chance that
your unit can be seriously damaged.
Another thing that could happen is
that your device can do something called “venting”. When this happens, harmful
chemicals can be released from the unit. If the device happens to not get
damaged up or vent, it could mess up your battery which
could end up messing up your entire device in the end.
As you can see, knowing Ohm’s Law
isn’t something that should be taken lightly. In fact, it’s really something
that needs to be known. Calculation and execution will not only help you build
better builds and better your vape sessions, but it will also help you stay
safe.
