| Law / Rule | In English (Dummies Level) | Real World Example | | :--- | :--- | :--- | | Ohm’s Law | Pushing harder (Voltage) moves more electrons (Current) through a tighter pipe (Resistance). | Why a thicker extension cord doesn’t melt. | | Right-Hand Rule | If you point your thumb in the direction of electric current, your fingers curl in the direction of the magnetic field. | How to tell which side of a wire is North. | | Faraday’s Law | The faster the magnetic field changes, the more electricity you make. | Your bike dynamo. Spin it slow = dim light. Fast = bright light. | | Lenz’s Law | Nature hates change. The induced magnetic field always fights the original change. | Magnetic braking in roller coasters. | | Maxwell’s Couplet | Changing electric field creates a changing magnetic field, which creates a changing electric field... forever. | Radio, WiFi, Light, Microwaves, X-rays. |
From longest wavelength to shortest:
- Want more current? Increase voltage or decrease resistance.
- Worried about overheating? Current² × Resistance = Heat (keep that in mind for extension cords).
