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: A small transformer used in a foundry has 550 primary turns and 20 secondary turns. Initially, the switch on the secondary side of the transformer is open, so there is no connection between the two ends of secondary coil.(a) What is the voltage difference between the two ends of the secondary coil, Vs, if a direct current potential of Vp 120 V is placed across the primary coil? (That is, the frequency of oscillation on the primary is zero.) (b) What is the voltage difference between the two ends of the secondary coil, Vs if Vp is 120 V and the frequency of oscillation on the primary is 60Hz? (c) Now equipment powered by the transformer is put into use and the switch is closed. A resistance of 14 Ω is placed between the two ends of the secondary coils. What is the current through the secondary coil? (d) What is the current through the primary side of the coil with the switch closed? Thanks so much!!: A. Zero, since dc current does not have a varying magnetis field. B. 550/120 20/ X 4.3636volts Ne /E p Ns / E s C.4.3636v / 14 .311 a. Es / R t A s D. .011 amp if the transformer is 100% efficient

Q: i have learnt from engineers that welding transformer is different from power transformer. welding transformer's current will be high.but its load will be low.my actual doubt is current is always proportional to load.then how we can justify this logic that welding transformer's current rating is high and its load is less.: the main difference of the two transformer are the manner of how they deliver their output. Welding transformers are capable of delivering huge amount of current. This is due to the fact that huge amount of current facilitates the melting and welding of metals. On the other hand, power transformers are mainly used for power supplies and therefore requires a stable amount of current to avoid current surges and voltage has to be regulated such that it can be used for consumer electronics.

Q: Usually the life of the transformer is called 20 years, is there any GB requirements? If there is a specific in that standard inside. Thank you for your thanks: I can only give you in the transformer industry, we all agree that the argument: 1, before the transformer, the oil inside the transformer and air direct contact. As the transformer in the thermal expansion and contraction, the oil up and down fluctuations, we called the transformer in the breath, an increase of oil and air contact opportunities. The moisture enters the inside of the transformer. So that insulation is reduced. Under normal operation and maintenance, the transformer is guaranteed to have a life span of 20 years. 2, the current transformer, to take a fully sealed structure, oil pillow with sealed pocket, so that the transformer oil is not in direct contact with the air. Under normal operation and maintenance, the transformer life is 30 years

Q: I just saw the movie and it has left me with a thirst for more on the story of transformersbut where can I turnComics, animated series?Thanks: Almost anywhere you go, you're going to get a slightly different story than what you got in the movie. If you really want something that fits in directly with the movie continuity, publisher IDW did a series of movie prequel comics which are probably available as a trade. For TV shows, the closest thing to what you saw in the movie is the original 1980's animated series, which is available on DVD. Beast Wars and Beast Machines both reference the 1980s cartoon (the former more than the latter) and Beast Wars at least is worth watching. Since then, there have been a number of largely terrible dubbed anime TransFormers shows airing in the US, which I would reccommend you skip. There are also a few shows that aired exclusively in Japan, of varying quality. And there's a new animated series coming out sometime next year which I think could be quite good. In terms of comics, you have the original Marvel series, some of which has been reprinted in trades, the Dreamwave series (which I personally did not care for), and the current IDW books, which I really enjoy. IDW covers a lot of different parts of the TransFormers mythos (G1, Beast Wars, movie, etc.) so you can pick what most interests you.

Q: hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated: Solder the joints!!!!It is OK to use the old connectors!!!! Be sure that the power of the new transformer it is the same with the power of the old one.

Q: Hi i'm considering starting to read comics. transformers comics to be exact. i live in ipswich so i walked into my local store (central city comics) there was alot to choose from and i know that there is loads of transformers comics out there I need some advice on starting a collection: just okorder

Q: How do I show the effects of putting a resistor in series with the primary of a transformer.Currently the transformer drops 120 to 6Putting the resistor on the 120 side what would happen? I am assuming it would drop the 120 down to some value which would then affect the secondary but I would like some numbers: An ideal transformer changes impedances by a ratio which is the square of its voltage ratio (which is also the winding ratio). So in your case you drop from 120V to 6V. The voltage ratio is 20:1. If we square that, we get a ratio of 400:1 for impedance transformation. This means a 400 Ohm resistor in the primary circuit will look like a 1 Ohm resistor in the secondary circuit. Please note that putting resistors in front of or behind transformers is generally not a good thing. It rarely ever makes things better and it almost always screws things up. If you need a different voltage, you have to change the ratio of the windings.

Q: A stepdown transformer is used for recharging the batteries of portable devices such as tape players. the turns ratio inside the transformer is 13:1 and it is used with 120 V rms household service. if a particular ideal transformer draws 0.350 A from the house outlet, what are the voltage and the current supplied to a tape player from the transformer. How much power is delivered?: I'm not going to do your homework for you, but here is how to set up the problem. Given: Input Voltage 120 V Input Current 0.350 A Turns Ratio 13:1 For an ideal transformer, VA(in) VA(out) Transformer turns ratio can be computed as V(in) ÷ V(out). Use algebra to solve for Output voltage. Output Voltage Input Voltage ÷ Turns Ratio The turns ratio can also be computed as I(out) ÷ I(in). Again, use algebra to solve for the outut current I(out) Output Current Input Current x Turns Ratio This is an AC power problem, so we have to either assume unity power factor, or label our power calculations as apparent power (VA). Apparent Power Voltage x Current As an ideal transformer, you can calculate the power on either the input or output side of the transformer. If you get different numbers, you did something wrong. Power V(in) x I(in) Power V(out) x I(out)

Q: assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain: In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.
