## The Electrifying Formula

Behold, the electrifying code formula that powers Joule heating:

```
Q = I² * R * t
```

Yes, you read it right! This formula helps us calculate the amount of heat (Q) generated when an electric current (I) flows through a resistor (R) for a certain time (t). Now, let’s dive into the mesmerizing realm of Joule heating calculations!

## Categories of Joule Heating

From tiny resistors to massive electrical grids, Joule heating finds its place everywhere. Here are some categories with a dash of imperial units:

Category | Type | Range (Imperial) | Joule Heating (Imperial) |
---|---|---|---|

Everyday Wonders | Household devices | 0.01 W to 2 kW | 9.6 BTU/hr (Space Heater) |

Industrial Giants | Machinery | 1 kW to 1 MW | 3.41e+7 BTU/hr (Arc Furnace) |

Cutting-Edge Tech | Electronics | 0.001 W to 100 W | 341.2 mBTU/hr (Laptop) |
