Q: What is Ohm's law in vaping?

Ohm's Law is basically the rules of the road that prevent your battery from turning into a homemade grenade in your pocket. It is the mathematical relationship between voltage, resistance, and current. Simply put: if you demand too much power from a battery that can’t handle it, it ends in fireworks—and not the kind children enjoy. Technically, we use the formula U = R x I . In mechanical vaping, this is vital for calculating if your battery's discharge (in Amps) can handle your coil's resistance. Don’t play sorcerer’s apprentice: always check that your build respects your battery's Continuous Discharge Rating (CDR) to keep your fingers attached to your hands.
