Vaping safety is the most important thing when it comes to hybric devices/mechanical mods vaping. You may have learned Ohm’s Law at school, but do you know how to use it when you make your own coil? In this article we’re going to show you the simplest thing you need to know about Ohm’s Law for vaping safety.
As we know, three fundamental elements of an electric circuit are voltage(U), current(I) and resistance(R). The voltage means the voltage of your battery, current means the amperage drawn by the coil and resistance is the resistance of the coil. The relationship between those three elements is U=I*R. Do some transforms we have I=U/R and R=U/I.
Generally speaking, a mechanical mod has a rated voltage and current. If the working current is bigger than the rated current, the battery may be damaged.
For example, a 4.2V battery has a a 10A current limit, according to Ohm’s Law, the smallest coil resistance that you can safely run without exceeding the CDR of the battery is R=U/I=4.2/10=0.42ohm. So anything lower than 0.42ohm will make your battery risk exceeding the current limit of it. But I would like to make coils more than 0.47ohm because my target current is 9A, which is definitely safe for the battery.
Not like regulated devices, unregulated devices/mechanical mods do not have protections as regulated devices do. So getting to know more about Ohm’s law becomes very essential. Vape on, vape safe.
