Q: I know that the ratio of primary turns to secondary turns is the multiplying factor in voltage. So if you wanted 100,000 volts from a 10 volt source could you potentially do this:4 transformerseach transformer has 10 coils in primary and 100 in secondaryThe output of each transformer's secondary is connected to the primary of the next transformer so that you get 10*10*10*10 or 10,000 as your multiplying factor.Would this work?or do you have to do it the hard way and wind 10 coils in the primary of a single transformer and wind 100,000 times in the secondary?: Yes, you can cascade transfomers. The efficiency might be lower, but it will work to a point. Note also that the current will be proportionally lower. The main problem will be the insulation strength as the voltages get higher: if the insulation isn't strong enough arcing will happen. That 100kV stage needs to be very, very robust - in fact, it probably isn't even feasible at a 1:10 turns ratio because its primary voltage is too high (10kV) and so will need ridiculously thick insulation and/or a lot of turns - engineering such a beast is certainly beyond the casual experimenter. The smart money says forget it. There's lots of ways to generate high voltage besides cascaded transformers. Techniques using flyback coils and capacitive discharge for example can easily get you to 50kV or more (this is, for example, how a Taser makes its HV.) I've included some links below. And please, be very, very careful this stuff can kill you.

Q: I got stuck in a problem while solving the previous exam question for my courseTwo transformers with unequal turn ratio and unequal ratings are connected in parallel and have the same secondary voltage. How will the load be distributed between them? Hence find the circulating current.I know how to find the circulating current when the secondary voltages are different. But how can there be a circulating current if the secondary voltage is same?And I know about the load distribution being inversely proportional to the line impedance of the transformers, but what will be the change taking circulating current into account?: If I understand this correctly, then you have this situation, let T1 be the first transformer and T2 the second one The input voltage is connected to the primary of T1 The secondary of T1 is connected to the primary of T2 the secondary of T2 is connected to the load If the secondaries are at the same voltage then T1 secondary voltage T1 primary voltage T2 secondary voltage. This can only happen if the turns ratio of T2 is 1:1, i.e it has the same number of turns on the primary and the secondary. Does that help?

Q: 440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.: The most common purpose of a power electronic transformer is to convert alternating current (A.C.) power from one A.C. voltage (or current) to another A.C. voltage (or current). Another common purpose is to provide electrical isolation between electrical circuits. Power is the product of voltage times current. Power transformers do not change power levels except for parasitic losses. Input power minus parasitic power losses equals output power. Ideal power transformers have no losses, hence output power equals input power. Increasing the output voltage will decrease the output current. Electric utilities prefer to transmit electricity at low current values to reduce resistive losses in the power transmission lines. Lower currents also permit smaller size transmission cables. A power transformer is used between the generating equipment and the power line(s) to step-up (increase) the transmission voltage (to high voltage) and decrease the transmission current. Distribution transformers, which are power transformers, are used to step-down (decrease) the voltage to voltage levels needed for industrial and household use

Q: I am going to see Transformers tonight at an 8:00 pm showing. Do you think there will be a big line to see it? Should I show up earlier to get a good seat or do you think going a 1/2 hour before the show starts, like I usually do, will be enought time to get good seats?: If I were you, I would wait until the movie was out on DVD. This way, you can see it whenever you like. Who knows? You just might enjoy it.

Q: Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better: Oil-immersed power transformer is one of the company's leading products, the original Ministry of Machinery Industry planning in Shandong Province, 220kV and below the production of the only key power transformers. Product voltage level 6 ~ 220kV, capacity 30 ~ 360000kVA, including 23 series, more than 200 varieties, more than 1,400 kinds of specifications, the technical performance indicators all meet the national standards and the International Electrotechnical Commission standards. The company has designed and manufactured the first domestic 110-kilovolt 31500 kVA three-coil aluminum transformer. Since the 1982 production of 220kV transformer, the product has been used in sunshine, Taizhou, Jiangxi and many other national key projects

Q: I know there was Transformers the animated series, Transformers cybertron, and Transformers energon, but were there any more?: Transformers Generation 1 (G1) Transformers Generation 2 (G2) Transformers: The Headmasters (made in Japan) Transformers Super God Masterforce (made in Japan) Transformers: Victory (made in Japan) Transformers: Zone (made in Japan as one-shot OVA) Beast Wars: Transformers* Beast Machines* Beast Wars II (Japan only) Beast Wars Neo (Japan only) Transformers Robots in Disguise (Car Robots in Japanese version)** Transformers Armada (Micron Legend in Japanese version)* Transformers Energon (Superlink in Japanese version)** Transformers Cybertron (Galaxy Force in Japanese version)* Transformers Animated** Transformers Prime * Ones I've seen and completed in English version (though I saw Beast Wars/Machines in another language). **I've seen them in English version, but dropped them after a few episodes. All others I've only heard of them. I think these are it. Hope I didn't miss anythough I think there are some old Transformers movies (I don't mean live action ones), but I don't know how many are there, as I never seen the old Transformers series.

Q: I am building a simple circuit and was wondering what is the difference between a coil and a transformer? Also, in my circuit I have a generator. My generator is made up of a coil and magnets. I would like to know do the amount of turns my coil is determine the power of the generator? When I select the gage wire I am going to use we that determine the amount of volts and current I can gain from my generator?: A transformer is nothing but a magnetic core on which two isolated coils are wound. Power of generator depends on many factors 1. Size and strength of magnet 2. Size and magnetic properties of iron parts 3. Rotating coils, speed, diameter, length. Gage wire is chosen based on volt / ampere considerations, not the other way.(gage does not decide voltage and ampere of the generator)

Q: how could I describe the physics of transformer?: A device by which you can increase or decrease the available AC mains voltage.

Q: I have a few questions about flyback transformers: How high of a frequency can they go without alot of losses?Can I get a negative High voltage by reversing the polarity of the primary?How can I make the flyback safe from the capacitive charge that it holds?: The flyback transformers used in TV's work at about 15000 hertz (the horizontal scan frequency). The transformers used in switching power supplies are smaller and work at a higher frequency, but they normally have a low voltage output. The transformer produces a high AC voltage, and a rectifier diode changes it to DC. Reversing the diode gives you a negative output. The picture tube provides capacitance to smooth out the voltage and holds the voltage for a while after the power is turned off. If you don't use a picture tube, you might need a capacitor if you want a steady output voltage. Shorting out the capacitor will remove the voltage.
