Welcome to Vaping Hardware’s Ohms Law Calculator!
For those of you unfamiliar with Ohms Law, this calculator allows you to determine whether the coil, tank and mod you’re using will work safely together. This is especially important when using a mechanical mod or unregulated device.
Just fill in two of the below fields and the calculator will work out the rest for you!
If you’re unfamiliar with Ohms Law and how it relates to battery safety, please take a look at our guide to Ohms Law!
Please note, you only need to enter two of the below values. If you enter three the calculator won’t correctly work out the remaining value.
We’ve included a handy FAQ at the bottom of this page!
Enter two values into the form below:
It’s always useful to at least have a basic understanding of Ohms Law as it relates to vaping. Especially when you’re using a mechanical/unregulated vaping device or building sub-ohm coils with a resistance of less than 1ohm. Ideally, you should be aware of the correlation between resistance, current, voltage and power to prevent drawing excessive current from your battery.
For obvious reasons, putting too much strain on the battery you’re using is not a good idea!
Using Ohms Law, Voltage (V) = Current (I) X Resistance (Ohms). Alternatively, Voltage can also be derived from Power (W) / Current (I) or the Square Root of Power (W) X Resistance (ohms)
Using Ohms Law, Current (I) = Voltage (V) / Resistance (Ohms). Alternatively, Current can also be derived from Power (W) / Voltage (V) or the Square Root of Power (W) / Resistance (ohms)
Using Ohms Law, Resistance (Ohms) = Voltage (V) / Current (I). Alternatively, Resistance can also be derived from Voltage (V) Squared / Power (W) or Power (W) / Current (I) Squared
Using Ohms Law, Power (W) = Voltage (V) X Current (I). Alternatively, Power can also be derived from Current (I) Squared X Resistance (Ohms) or Voltage (V) Squared / Resistance (Ohms)
