The relation between Resistance and Voltage Explained


The relation between Resistance and Voltage Explained

Vaping has evolved so much that its considered as an individual sport, the complications in the sports itself have evolved too. The question about the all-important terms in vaping like Resistance and Voltage has risen again and again on different forums. While some of the people who are good at vaping are familiar with this term, but most of the newcomers have a problem recognizing these terms, let alone their importance.

Before we jump into details, I would like to add that in recent times of research and development where variable resistance and Temperature Control Mods are widely available in the market, there is almost no need to know about the science behind these terms. Although, if you want deeper understanding of vaping in general and increase your knowledge as a vape geek, this post is for you.

Resistance and Voltage as scientific terms

Science defines (Ohm) as the measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance and is the ease with which an electric current or voltage passes (V). Now, obviously you can find this term online too. The explanation of Resistance can be made by taking the example of a large water pipe with a valve on the start to control the flow in the pipe. The tighter the valve is, the difficult it makes for the water to pass. Now replace the water pipe as coils, water as current and valve as you resistance. The greater the resistance, the less the current would be allowed to pass.

What does resistance mean when vaping? Well, on the most basic level, it means how much current you want to apply to each one of your puffs. If you increase your resistance, less current would pass to each one of your puffs and vice versa. Now increasing or decreasing these variables would definitely have an effect on how you vape. The effects of these are mentioned below.


Varying your resistance varies how your vaping experience turns out. Lowering the resistance results in the following;

  • Coil becomes heated quickly as more current is passing by
  • The temperature of the vapor may increase
  • The intensity of vapors may increase
  • Larger and denser clouds are formed

However, there are some negatives too, that come along with  lowering the resistance;

  • More battery is used because more current is used in each puff.
  • Because the usage of the battery will increase, its life may decrease.
  • Atomizer’s life will be effected
  • Dry Hits may increase (How to decrease dry hits)
  • E-Liquid will be drained more quickly.

On the contemporary, if you increase your resistance, you get;

  • The lesser battery is used on each cycle, which will increase your battery life. (Increase your Battery Life Now!)
  • E-Liquid will run for a longer period of time.
  • Chances of dry hits are greatly reduced.

Negatives associated with this are:

  • The cloud size would be smaller
  • The less current flow used in each puff
  • Vapor temperature may be lower
  • Atomizer would create lesser heat
  • The intensity of flavor may decrease

Hence, there is no hard and fast rule of what voltage to apply when vaping. Some of you might like colder clouds and some of you might like it warmer, hence everyone depends on your preference. You have the control, set the variables as you like. However, to further help you to get started a resistance/voltage chart is attached at the end of this post. Happy vaping!
