## I'm sleeping with my head in a 6 milliGauss AC magnetic field.

So there's a powerline outside my bedroom window, and I thought, huh. Turns out I'm sleeping with my head in a 6mG AC magnetic field. Help me use physics to stop caring.

## A Potentially Electric Question

What is "electric potential"? I've dug through the internet, gone to tutoring, asked my teacher, and nothing has helped.

## Power Grid: The Game is way more fun than this.

Explain alternating current distribution across "the grid" to me in terms an educated layman can understand. Specifically, I have a question about how to talk about which power plants are providing power to a particular consumer.

## Drill It Into My Head

Help me understand electricity and physics and how they apply to motors. I have my head around electricity basics and electromagnetism, but I have a few unanswered questions about the more subtle aspects.

## V=I*R

Physics filter: The original fuse for an Ikea lighting system was rated for 6.3A and 250V. After a power surge, I noticed that the fuse had been toasted. Upon visiting 3 hardware stores, the best I could find was a similar fuse rated for 3.15A and 125V. Since V=I*R, it follows that the resistance is identical when the original fuse is compared with the replacement. Does this mean that these fuses are functionally equal?
