WHilst they may not be necessary for the first time vaper puffing on a cigalike, the relationship between vaping and Ohms is one that is easy to overlook. Vaping is known for its simplicity and flexibility, which is why the Vape Shop Dartford has such a loyal fan base. There are plenty of people coming into the store and asking questions about vaping, because despite the surface simplicity, there is a lot of complicated science which makes the pastime what it is today.

Where do Ohms fit in?

Ohms are a measurement of resistance in a circuit. An ohm, or the resistance has a relationship with the wattage and the voltage in the circuit, affecting the amount of current and energy output being passed through. The watts or current in the circuit represent the input of electricity, which is fed through the system and meets resistance from the various components within it. The output of the system is known as the voltage, and the resistance measures how much energy is lost through the circuit.

What is Ohm’s law?

Ohms were first conceptualised and organised into a formula by Georg Ohm in his research books published in 1827. However, the idea of a relationship between the wattage, voltage and resistance of a circuit had been floated for a hundred years before. It was Georg Ohm who took the ideas and focussed them into a formula.

His formula stated that to find any missing unit in a circuit, you can simply use Current = Voltage / Resistance or

I = V / R.

This formula can help us to understand the relationship between the three units of measurement, and are extremely useful when using a variable wattage or a variable voltage vape device.

These variable wattage or variable voltage device are devices with which you can adjust the maximum and minimum power settings of your vape device. This means that you can calibrate the device to the sweet spot that you like to vape at and Ohm’s law will allow you to read and calculate the other units in your circuits.

What is sub ohm vaping and is it right for me?

Sub ohm vaping is when the resistance or ohms of your circuit are under 0.1. Most vape devices can range from between 0.1 ohms and 2.4 ohms as the highest resistance. The higher the resistance, the less vapour produced as the power is being undercut by the buffer of ohms.

Sub ohm vaping is when the ohms are lowered, meaning that more power flows through the device and creates bigger clouds of vapour on the exhale. This is especially useful if you are getting into direct to lung vaping, and are used to high powered vaping sessions. This does use up more battery and vape juice however, so may not be for everyone, especially those who are not used to vaping thick plumes of vapour.
