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

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?
