- Q: i heard a new was coming out ,i hope so ,the first two rocked!!!
- Transformers 3 is estimated for a July 1, 2011 release.
- Q: How to test a Current Transformer (CT) ? thanks in advance
- BE CAREFUL! A Current transformer can generate very high voltages - hundreds or even thousands of volts - if it doesn't have a load! So the first rule of safety when working with CT's is to ALWAYS have a load on it!!! Start off with a load resistor, say a 10 Ohm, 5 Watt resistor. Connect the resistor directly across the CT's winding. Then read the voltage across the resistor. Run a single wire through the CT, and put a small current - say 1 Amp or so - this can be one of the 2 wires feeding a 100 Watt light bulb. This will give you a little less than 1 Amp. (Actually, by Ohms law: 0.8333 Amperes) P 100 E 120 I 0.8333 Amps R Then the voltage developed across the resistor with a known current will tell you the sensitivity of the CT. It is likely that the CT is made to connect to an ammeter - which has a resistance of only an ohm or two - which has been calibrated for that CT, in which case the voltage you get across a 10 Ohm resistor could be quite high. NOTE that a CT, like any transformer, only works with AC.
- Q: I am build a band pass filter but I am wondering if one of the inductors in my filter can act as a transformer at the same time. I'm assuming not since it would be sending all its magnetic energy into the secondary rather than back into the primary. Can someone confirm this for me please? Also, if it DOESN'T act as an inductor than would it be okay to put it in parallel into my filter? Or do I put it in series? Where do I put it lol?Thanks
- A Transformer can be both a car and a robot
- Q: Are there any transformers action figures that arent for little kids like from the movie and are collectables? LINKS?
- I used to play international of Warcraft. I remember being point 60 (the max on the time), and looking after agency in Ironforge. It replaced into annoyingly effortless to have low point newbs whisper me with, Gold Plzzz!!! and i desire 2! and am i able to have some gold? It replaced into rather stressful.
- Q: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.A How many turns of wire does the secondary coil have?B When the transformer is running at full power, what is the current in the secondary coil?C The current in the primary coil?I know what equations I would use, but I don't have enough information to use them. Can someone at least set these up and show me how to plug the numbers I have into the correct equations?

- Q: I wa watching the films and was wondering how the transformers just spawn more and more. For example soundwave made the panther thing then it made the thin robot and all those construction guys too, then they made the huge robot with the balls.
- Haha, well from what I remember, the bodies were assembled on cybertron. But that wasnt it. In order to create actual life the transformer needed The Matrix, an orb (or in the live action movies, a slender metal thingy?) which would allow a spark from the Allspark (which is essentially transformer heaven if I remember correctly) to enter the body and give it life. This can also reanimate deceased Transformers. The only other times I remember transformers coming to life in the show, is when the autobots found the Dinobots and somehow brought them back to life? Then there was the world eater, Unicron, who was able to upgrade other transformers. An example would be the transformation of Megatron into Galvatron made possible by Unicron.
- Q: I would like to use this circuit to power arrays of high power LED'sI understand the properties required to power LED'sI have beginners knowledge in electric circuits and have done some research on this circuit. I have come across several posts stating it is dangerous to connect this circuit straight to mains power. I don't understand is what makes it is so dangerous?AndIf possible, how can it be made safe without using a transformer.
- As a measure of safety, one of the lines of the mains is at earth potential. So if you stand on earth and touch the other wire, you will get a shock. the voltage between earth and the other line is 110V. Thus the source is not a floating one but a ground referenced one. If you use a 1:1 isolation transformer, then you can touch either end of the secondary as the other end is floating. SO you will have no shock hazard. You cannot take the ac mains as floating. It is not like a battery kept on a wooden table. One end of this 110V battery is already grounded, if you want to look at an analogy. And the electricity supplier grounds one end to ensure safety, and if the current to safety earth is higher than about 5mA, a protecting mechanism is invoked. as in earth leakage detectors.
- Q: Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.
- I was in Germany for 2 years they are 220v also. I had a 110v step down and it worked fine with a TV VCR and a electric razor.
- Q: Is the transformer a power adapter?
- No, the transformer should be a device that performs impedance matching in order to achieve maximum power transmission. In turn, "power adapter is a transformer" is also unsatisfactory, at least the general power adapter contains a transformer. As a power adapter requires a common power supply into a device required power, voltage, current, impedance and other aspects of the match, of course, it needs a transformer. Since it has the function of changing the voltage, call it "transformer" is no harm. I would like to say that the power adapter is not only transformer, it needs to achieve in addition to the voltage other than the parameters of the match, for example, the most simple general-purpose DC adapter in addition to transformer that there is a "rectification" process. The transformer, narrow sense that it is just a component only, like resistors, capacitors, transistors and so on.
- Q: a lamp is connected to a secondary coil ( 80 turns) of a transformer by long leads which have a resistance of 2.5 ohms. Primary coil( 1600 turns voltage is 220v). the power input to the primary coil is 44w. 1) what is the voltage across the secondary coil2) what is the current across the secondary coil3) what is the electrical power dissipated in the lamp
- Assuming perfect transformer. turns ratio 1600/80 20:1 secondary voltage is 220/20 11 volts primary current is 44/220 0.2 amps secondary current is 0.2 x 20 4 amps drop across wires is 4 x 2.5 10 volts. This assumes the 2.5 ohm number is for both leads, not each. voltage across lamp is 11v – 10v 1 volt power in lamp is 1 v x 4 a 4 watts. .
