Also, with the formula I stated earlier, it was a maximum theoretical output of an amp. That means with those facts, the amp cannot pull more current (amperes) than its fuses w/o popping them. Therefore the abosolute maximum power output cannot be larger than its input right?
Two 8 ohm 1000watt copper coils from radioshack - drop them in distilled water and have at it. I have managed to shatter 3 or 4 glasses with this method.
Peak current can exceed the fuse rating as automotive and maxi fuses have very leniant tolerances example: a 30 amp blade fuse has +20% @ 5 second / +50% @ 1 second etc..
The fuses dont instantly blow at their rated capacity - Since each manufacturer has its own tolerances it would be very difficult to use that as an accurate gauge.
