What is Ohm’s Law for Vaping?
Ohm’s Law states that an electrical current is proportionate to the amount of voltage across it. The German physicist Georg Simon Ohm was the first person to verify this relationship. However, this definition can be hard to understand, which is why teachers and professors use the “water pipe analogy” when explaining this Law.
Electrons moving through wires are analogous to water moving through a pipe. More water moving through a pipe means more pressure is being applied to the pipe. Therefore, if a lot of water is moving through a pipe, a bigger pipe is needed.
The same principle applies to electrons moving through an electrical wire. If the voltage (water pressure) moving (current strength) through the wires is high, lower resistance wires (bigger pipe) are needed.
In a vape, there is an electrical current flowing from the battery to the coils that vaporize the nicotine. Therefore, proper coils (a big enough pipe) are needed to suit the flow of electrons from the battery.
Why Vapers Should Know Ohm’s Law
Vapers who use unregulated mods need to know the principles behind Ohm’s Law. If a battery is putting out too much current, it can vent. A venting battery means that chemicals are being ejected from the battery under high pressure, which could cause an explosion.
A vape that explodes next to someone’s face or in his or her hands could cause severe disfigurement. In one notable case, a Fort Worth native died when his vape exploded in his face.
This problem can easily be avoided by knowing what currents wires can and cannot handle. Before vaping a new unregulated mod, read the device’s specifications and manual. The specifications and manual clearly state the battery’s minimum and maximum resistances. Never go above or below these tolerances.
The Power Triangle
Those who do not like the water pipe analogy will like the power triangle. It is similar to the speed, distance, and time triangle used by mariners and pilots to navigate.
However, instead of having speed, distance, and time in the triangle, it has voltage, current, and resistance. This triangle/chart can be used to calculate voltage, current, and resistance.
It is also possible to use an Ohms law calculator for vaping. An Ohm law calculator vape is more straightforward than doing the math on paper.
Calculating Current, Voltage, and Resistance
The formula for calculating an electrical current consists of three variables: voltage (V), resistance (R), and current (C). Once the variables are substituted with the voltage, resistance, and current measurements, the problem can be solved.
Here is a formula for calculating an electric current. For example, if four volts (V) are being generated through a cord with a resistance (R) of 2 ohms, the formula would become:
C = 4/2 or C equals 4 volts divided by 2 ohms
Four divided by two equals two, so the answer is two amperes are running through the cord.
C = 4/2
C = 2 amperes
Keep in mind that a good vape tool for measuring electrical current is an ammeter.
The formula for calculating resistance is also similar, as it calls for division. The formula is:
R = V/C
Use the same numbers as above to solve the problem. If a battery four volts were running through a cord and the current is two amperes, the formula for figuring out the resistance is:
R = 4/2
Again, divide volts by current, and the answer is:
R = 2 ohms
Calculating voltage requires multiplying the current by the resistance. For example, there is a current of four amperes traveling through a four ohm wire. Four amperes are multiplied by four ohms. The answer is 16 volts.
V = C x R
V= 4 x 4
V = 16
Calculating the wattage (P) also requires multiplication, and the formula is:
P = V x C
If two volts are traveling at a two ampere current, the formula would be:
P = 2 x 2
Multiply two amperes by two ohms. The answer would be:
P = 4 watts
Frequently Asked Questions
What Are the Safe Ohms in Vape?
As earlier stated, the safe resistance is stated in the manual and the specifications. But, again, it is important to emphasize not to vape with coils that have lower or higher resistances than what the devices can tolerate. Someone who does this is risking a serious accident.
What Wattage Should I Vape at 0.4 Ohms?
0.4 ohms is what is known as “sub-ohm” in the vaping community. A resistance of 0.4 ohms is ideal for vaping freebase nicotine at high temperatures to generate thick clouds. The lower the resistance, the hotter the coils, and the thicker the vapor.
Is Higher Ohm Better for Vape?
Higher or lower resistances are not better or worse. It all depends on the user’s preferences. Someone who likes producing thick clouds should purchase low resistance coils.
Someone who likes vaping salt nicotine liquids with a tight airflow should get a pod that runs at 1.0 ohms or higher.
