Ohm's Law - a Quick Guide

Ohm’s Law is a part of vaping that tends to be over lookedquite frequently when starting your vaping journey, however it is informationthat is integral to implementing safe vaping practice. We understand that Ohm’slaw as a mathematical calculation can be quite confusing to understand and howit can be applied to vaping. By the end of this blog we hope you will be ableto go on and vape happily and safely as well as learning something new!

What is Ohm’s Law

So Ohm’s Law is very simple to remember if you can rememberthe below image:

Remember this image and you’re set to go, put a copy in yourwallet/purse, stick on your fridge or simply save it in the memory bank.

The Calculation

From here, you can find out any of the values as long as youhave the remaining two, demonstrated by the image below:

So in short, as an example, if you want to find out the amps(represented by the “I”) then simply cover it with you finger and carry out thecalculation required on the remaining values, in this case that would beVoltage (V) multiplied by Resistance (R).

How is This Applicable to Vaping?

Knowing the above is all well and good, but how does itapply to vaping? Well, in short each battery and power output has a resistancerange that it is safely capable of powering. You wouldn’t want your battery tostruggle to heat your coil, nor would you want too much power running through acoil that can’t handle it.

So, arguably, the big one you have to remember is whetheryour battery has enough power to safely heat your coils. To work this out weneed to know the current (amps), which is represented by “I”, all we need to dois cover the “I” with our finger, leaving V / R or Voltage divided byResistance. You can find these out by using a dedicated meter or by screwingthe Atomiser onto your Regulated device, but be careful, you don’t want to firethe device yet.

Once you have picked your desired Voltage (variable wattagewill adjust your voltage based on the resistance of your coil) then divide theVoltage by the resistance of your coil and you will have the current (amps)running through the coil. You want your battery to have a high enough amp limitto accommodate this, we suggest that your battery has a capacity that is atleast 5 amps higher than what is required for your coil build.

Below is a the calculation used if you know the wattage butdo not know the voltage.
