Onceyou get your head around OHm’s Law, modding couldn’t be easier.

Whilst most vapers tiptoe around theintricacies of Ohm’s Law, they are truly missing out on the great powers andfreedom which it unlocks. The simple formula is the key to a lot of differentvaping experiences, many of which will bring a broader horizons to your vapingexperience. Whether you’re a vaping pro or new to the hobby, it will always behelpful to have a good grounding in Ohm’s Law. But what is Ohm’s Law, how doyou use it and how does it relate to your vaping experience?

Thehistory of Ohm’s Law

Using glass jars and tubes filled with saltsolution, the first experiments with Ohm’s Law dated back to 1781, when famousBritish scientist Henry Cavendish experimented with circuits, using shocks tohis own body to measure “electrification”. Fast forward 40 years and Georg Ohmwas publishing his results on resistance experiments. In the years 1825 to 1827he compiled his research in the book “The Galvanic Circuit InvestigatedMathematically”. Using a galvanometer and test wires, he managed to come up withthe main source of Ohm’s Law and refined it over a three year period. Sincethen, Ohm’s Law has become common knowledge and is used regularly in thescientific community.


There are several formulas which came out ofOhm’s Law, all of which give the basic principles to measuring and creating anelectrical circuit. The main concept behind it is the relationship betweenvoltage, current and resistance.

The current of a circuit, or amps, is the flowof electricity through it. The Voltage is the potential difference andelectromotive force, whilst the resistance,or the ohms of a circuit is themeasure of how difficult it is for electricity to pass through a circuit.

Ohm’s Law ties all three of these electricalcircuit elements together in the equation

Resistance = Voltage / Current.

This formula makes it easy to find one missingelement of a circuit and calibrate it accordingly. The applications of thisformula is used for all electrical circuits in the world, it becoming one ofthe most useful electrical formulas used today.

Vapingand Ohm’s Law

And one of the most recent and innovative usesof Ohm’s Law has been in the use and calibration of vaping mods. In vaping mods, the formula translates as

Amps = Battery Voltage / coil resistance.

Vape mods use variable voltages or variablewattages to increase or lower their power settings. This makes it useful tounderstand Ohm’s Law, making it easier to find the right vape setting for yourvariable mod. This also means that you can experiment with differentresistances in your coils, opening up an entire new dimension of vaping and anew understanding which wouldn’t be accessible without the use of Ohm’s Law.

How toapply it to a better vaping experience

Many of those who vape with larger devices areoften experimenting to find the best settings and juice balances for their ownpersonal tastes. Understanding Ohm’s Law will ensure that they have thenecessary tools to find this.

Variable wattage and voltage devices arealmost interchangeable in that they give you the freedom to change the currentflowing through your device. Whilst the variable wattage calibrates the outputof your device, the voltage will calibrate the input. These devices therefore,require you to understand the different formulas in Ohm’s Law to take fulladvantage of what they can offer.

Understanding Ohm’s Law will also ensure that you areusing your vape device safely. Adhering to the formula will ensure that younever stray from the boundaries of your circuit, keeping you safe from yourvape device bursting or short circuiting.
