1 Hz = 1 cycles/second 60 Hz is 60 cycles/second

Can you use a high voltage vertical pdu and change the plug to a 15amp plug? This would be for small servers and switches.

Hi TechTrainerNJ Team, is it possible that your animation is wrong? Between 5:29 and 5:31 is no change of flux in the coils (during the transition of the magnet from the LHS to the RHS of the coil) - So the Volt-Meter is supposed to show 0V instead of max Voltage. In a Wikipedia article below there is a change of direction when the magnet points to the coil... de.wikipedia.org/wiki/Datei:Simpel-1-faset-generator.gif Can you check and let me know please?

@@Ayrix06 there's a bunch of three phase videos from the engineering mindset and they have 2/3 of their animations incorrect, which is mind boggling. I think the intuition is: if you pretend the magnet is in the coil, Lenz's law makes the coil into a magnet. The "coil" magnet stays fixed, the other rotates. When it rotates, when the magnets match the orientation of the "coil" magnet, those are the zero points of the sine wave. When the bar magnet is 90° to the "coil" magnet, that's when the flux difference is peaking (or troughing). I think Feynman lectures may have a diagram... Can't recall.

@smokeybobca Жыл бұрын

Actually, I don't think you need Feynman. If you go to any (stupid) textbook that does that silly ideal AC generator and makes a single coil of wire rotate in a perfectly uniform magnetic field, it uses the similar arguments I had above, I think you get there. I really, really hate the textbook example because it'd be insanely hard to make that setup, and second it doesn't make the leap from this silly ideal setup to how generators are actually made (even if rotors have self-excited electromagnets instead of permanent magnets)... But I digress.

At positive half cycle, current flows from phase(line) to neutral following the path from higher potential to lower. You put a voltage tester on line, it will beep, on neutral, it wont. At negative half cycle the phase potential is lower than neutral so current flows in the other direction. So line becomes neutral and neutral becomes line. But, do you mean that we have supply in neutral during negative half cycle? In this case, why a line tester would fail to glow if it is tested over neutral line at the negative half cycle. Please explain.

Sorry but This is absolutely wrong the stationary electrons can't have any force just because of the magnet the only way to move the electrons is due to electric field.

Dude, how do you get the definition of Hz so fundamentally wrong in an 'informational' video? Hz is a measurement of cycles-per-second, not a measurement of the length of the period in a wave. To say "__ Hz/second" either implies either you think the electrical grid is in a state of accelerating AC frequency, or just fundamentally don't understand the unit.

im bit confused.. if ac moves forward and backward, how can it reach the load and return to neutral.. in term of domestic wiring

@florida995 3 жыл бұрын

Great question. I had the same question. After researching, I found that electricity in simple terms travels at nearly the speed of light which means that at 60 cycles per second the wavelength is 5000 km. So unless your utility or substation is more than 5000 km away (or 2500 km away for the neutral return) the electromagnetic energy will have long reached your appliance before the polarity reverses at the first cycle.

AC generators work on the principle of Faraday's law of ‘electromagnetic induction’. When the armature rotates between the magnet's poles upon an axis perpendicular to the magnetic field, the flux linkage of the armature changes continuously. Due to this, an emf (electromotive force, other known as, voltage) is induced in the armature. Notice, as the armature revolves between the magnet’s poles, upon an axis perpendicular to the magnetic flux, the armature revolves the opposing direction (opposite, or reverse). That’s how the AC output is generated.

You can't induce current on a wire by placing a magnet next to it. You need a changing magnetic field (either the wire moves or the magnet moves to generate changing mag field)

Usually you need a iron core with copper wrapped around it, and the magnet will pass close to the iron core and it'll induce the current on the coil.
