Battery safety guide
Ohm's Law is the basic electrical relationship behind resistance, voltage, current, and wattage. In vape hardware, it matters most when a shopper moves beyond simple pod systems into coils, tanks, rebuildables, or adjustable-power devices.
Start here
The simple version: lower resistance can draw more current from a battery, and higher wattage changes heat and vapour output. Regulated devices manage much of this, but advanced hardware still requires knowing what the coil and battery are being asked to do.

Full guide
Ohm's Law is commonly written as V = I x R. Voltage, current, and resistance are connected, so changing one part changes the rest of the setup. Wattage adds another layer because it describes power output and heat.
A coil's resistance affects how much power the device uses and how the vape feels. Lower-resistance coils are often used for higher-output setups, while higher-resistance coils are often used in tighter MTL setups.
Most modern regulated devices include protections and recommended wattage ranges, but that does not remove the need to match coils, pods, tanks, and batteries properly. Mechanical and rebuildable setups are a separate advanced category.
Use this guide as background, then shop by compatibility. If the product page lists coil resistance or wattage ranges, treat those details as the buying instructions.
