Q:even in a dc transformer, the cause varying current though not in polarity, can cause a change in the magnetic flux linked with a coil.: Using a transformer with a varying DC signal was done all of the time with vacuum tube amps. Checkout the output transformer in the attached schematic and you will see its primary is being fed from high voltage(B+) DC. The output from the secondary is AC. Using a transformer is another way of blocking DC and passing the AC component of a signal. Note this doesn't mean that the DC is being pulsed on and off, rather it is varying with the applied signal. You can liken this to the algebraic sum of an AC signal with a DC bias voltage. 50VAC signal goes from +50 to - 50 volts Place that on a 100VDC and the result is a DC voltage that varies from 150V to 50V.

Q:Transformer ratio and transformer ratio: Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship! In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1

Q:I have an an iPod touch with 3.0 and I installed a jailbroken app called Transformer. It makes thr iPod look like an iPhone. But when it resprings, nothing changes. Please Help!: I feel your pain, but Transformer only works on itouches with the firmware 2.2 or under. If your still want a iphone look-a-like this is what I did and I works great Maybe even better than tranfromer!: 1. Download iCall, textPlus, and Flicket off app store. 2. Download CompassF app off cydia. 3. Download theme iPhoney theme off Cydia 4. Download Better 3G WiFi (turns wifi bars into 3g) 5. turn on the 2 themes ATT bars will be added w/ iPhoney automadiclly 6. Download SBSettings, extras, and turn on the numeric battery. (like 3Gs) 7. Lastly, if you want to go that extra mile Im working on a Theme that changes the iTouch settings to iPhone ones with wallpaper on main page. And thats it, the Icons and names of the 3 app store apps should change to camera, messages, and phone. The spotlight should say, Seach iPhone and thats pretty much it. Not only does the phone work with wifi now looking just like the iphone dialpad, and so does messages. So I think this is better than Transformer and wont mess up ur touch like transformer would. Hav fun messing with your friends minds lol! :)

Q:does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?: I heard AprilI think.I'm not sure. Try looking on Google or YouTube XD

Q:I love the movie transformers and cant wait till part 2.Anyone know anything about it specifically???: I cannot STAND that movie. The live action version sucks so much c0ck and balls. The original 80s Transformers Movie animated version had WAY more robots and WAY more action. Mike Bay's piece of cinematic fecal matter had only a small group of robots who look NOTHING like the Transformers from the cartoon series, and it was all about that idiot Shia LeBeouf running around whining and acting like beyotch. Correct me if I'm wrong, but I paid to see a Transformers movie and got ripped off. The movie wasted my time with those stupid human characters, and the robots really didn't do much of anything. The story sucked and who actually gives a crap for Shia's character romantic life? Ugghh! What a turd of a movie painted and glamed up to look better than it actually was. Which is why I don't undertsand why people like this movie so much? It is an insult to the true Transformers fans.

Q:How much W?: Ee22 transformer can be 20W. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:I want to know how much the current will increase. But the transformers i'm looking at VCT VT10000 - 10,000 Watts Heavy Duty Continuous Use 110V / 220V / 240V Step Up / Step Down Voltage Transformer or 15,000 Watt Step Up and Step Down Voltage TransformerI figure the whats is the total possible power and if you divide the power by the intial voltage you get the current and if you divide by the out put voltage you get the final current? but what if you input doesn't equal 15000 watts or whatever the power is?: The rating of a transformer like this one is really in volt amps, not watts. This is because the winding losses are proportional to the RMS current squared. If the load current is not in phase with the voltage, the power is voltage times current times the power factor which will be less than V*I.

Q:10 (6) /0.4kv three-phase transformer what does it mean: Therefore, the decision to 60 and 35kV winding connection to be careful when the connection must meet the transmission system voltage phasor requirements. The connection between 60 and 35kV windings is determined according to the relative relationship of the voltage phasors. Otherwise, even if the capacity of the voltage ratio is also right, the transformer can not be used, connected wrong, the transformer can not be connected with the transmission system. 3). Domestic 10,6,3 and 0.4kV transmission and distribution system phase also has two phases. In the Shanghai area, there is a 10kV and 110kV transmission system voltage phase difference of 60 ° electrical angle, this time can be used 110/35 / 10kV voltage ratio and YN, yn0, y10 connection three-phase three-winding power transformer, but limited Three-phase three-core core. 4). But note that: single-phase transformer in the combination of three-phase group connection, can not use YNy0 connected three-phase group. Three-phase shell-type transformer can not use YNy0 connection.

Q:I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?: Yes, Transformers: Dark of the Moon follows Transformers and Transformers: Revenge of the Fallen. I don't think the story's so complex that you won't be able to follow it, but I would recommend watching the first two films if you have the time.

Q:I have 14 gauge wire and some 28 gauge wire. Do both lengths of wire have to be insulated? Is it as easy as winding the 14gauge wire top to bottom and then do the 28 gauge wire top to bottom also? I'm guessing this is a step up transformer because the battery is going through the 14 gauge wire and then the lightbulb is hooked to the 28 gauge wire?Does the direction on winding matter at all? Say, CW for the 14g and then CW with the 28 gauge?: ferrite rods are not customarily used for transformers. at RF they are sometimes used as a core for a loop antenna. your application sounds like an ignition coil as you need an interrupter on the DC input (like points on a car ignition). the primary wire (14 gauge) would just be a few turns and not likely to run the full length top to bottom, the secondary (28 gauge) would be a lot of turns like 10 or 20 times as many. direction of winding would not matter in this application as capacitive coupling between the windings should be insignificant. all wire has to be insulated as a shorted turn spoils the transformer effect. wire used for transformers is customarily insulated with lacquer as plastic adds too much bulk to make tight windings. if you already have bare wire, then you made have some success by dipping the wire in lacquer paint first. it sounds like you are duplicating a project you have seen elsewhere. without knowing the source, it is hard for us to guess what the circuit parameters need to be for the transformer. but as i pointed out initially, i am skeptical that you will get this to function in the manner you are expecting. AC power transformers of the kind that use these wire gauges always use a torroidal core ferrite, never a rod. static DC cannot be transformed at all.
