Even on my '71 Chevy, you could full-field the alternator by putting a straightened paper clip in a hole in the back of the case of the 60A alternator, the paper clip would ground out the field coils (normally handled by the voltage regulator) and then it would put out full power because it was...
Danger, it sounds like you're thinking of the regulator as a linear voltage regulator on the output of a generator, which is pretty much non-existant today.
If you look at a modern Delco alternator for example, it varies the duty cycle from 10% to 90% on a 400Hz pulsed signal that is...
Richie - creating an off-the-grid home or one that is grid connected so you can sell back excess power or use power on periods of sustained inclement weather is becoming slowly more popular. (selling back excess varies by state laws)
The reason its only slowly becoming more popular is that...
There are many different parameters that would need to be factored into determine this. If your target voltage was 130V, then you likely have a desired power output as well so you'd want to factor that into the calculations as well.
But the voltage produced would roughly be based on:
-The...
The second Furman has more filtering. They are spendy though, I'd like to either see like an ASTM standard and the test data or just experiment myself before spending that much, and then again wonder why I bought such cheap audio gear I'd need one as well if I was doing audio recordings for a...
A typical product market is vague, it makes it easier to sell product. Watch the episode of Seinfeld call "The Move" where Jerry needs to get his car fixed. In discussions with George, they essentially say that a honest auto mechanic is more valuable than other things, the car is just too...
The power conditioners come in a variety of configurations, from the 'surge protector' kinds with 5 cent MOVs that offer a tiny amount of protection for a tiny amount of time, to autotransformer types with multiple taps that switch to adjust the in/out ratio, to active switching power supplies...
Nice, hadn't thought about actually using the Curie to have a desired effect!
Too bad the thermal mass and energy required make it very impractical, but within the realm of possible.
Guess: Maybe the 1% just refers to a 20db reduction in noise put in laymans terms?

M: THIS ENGINE IS WHISPER QUIET AT ONLY 135dBA.
J: WHAT?
M: QUIET!
J: WHAT?
M: YEAH.

The AC you refer to is produced by a rotating magnet or coil of wire, and as it rotates it goes North-South-North-South and that creates the AC. A DC motor (that can also be a generator) uses brushes on a commutator that switches the coils so that the north is always on one wire and same for...
Look halfway down this page, the resistor has an aluminum heatsink already attached in the diagram.

current^2 * resistance is power dissapated in resistor.
13^2 * 1 = 169W!
But when you insert that resistor, it becomes part of the circuit...
Look at brushless DC motors like used on some computer fans - the switching of north/south poles on the stator is handled by transistors that switch back and forth instead of brushes and the armature is permanent magnets.
If you take a universal motor like used in a corded power drill, it...
If his load is inductive, the in-rush current will likely cause the inverter to shut down.
Also, the length of time per car battery is going to be low, like maybe 15-20 minutes (getting better with more of them with Peukret factor not hurting as much). A car battery might have a lot of...
Since the wankel generally has low compression (note that Mazda simply spins their RX8 to 9000RPM and put a turbo on the RX7 to increase power) it will have one drawback to using H2 - it will loose efficiency because of H2s lower energy density, so there's 15% loss compared to gasoline. In a...
Averagesupernova - couple things:
1) If we're talking about overdriving, this would be exceeding the manufacturer specifications. This is incredibly common, its the promise of free increases in performance.
2) Amplifier EEs know full well the crest factor of music means that full power...
