Q:Should I get an Asus Transformer Prime or an Ipad 2?
Ahh two very highly rated tablets that each have their own pros and cons I'm an owner of the Transformer, and I love it. It's got very good touch response. Camera quality is poor, though. If the camera doesn't matter to you, then that shouldn't be a problem. With the docking keyboard on, you've got basically a netbook that can play apps. The Transformer's keyboard obviously makes it a lot easier to type, and since you're looking for a tablet for schoolwork and are already accustomed to Android's interface, the Transformer is a nice bet. iPad 2 is in my opinion highly overpriced. It has slightly smoother touch response and a much higher quality camera. But it does not have a docking keyboard. The touch response and camera quality are the only two things that make the iPad 2 better than the Transformer. Of course, you are also accustomed to a wider app market with the iPad. Since you are looking at a tablet for schoolwork, I would say the Transformer is right for you. (I typed that whole thing with my Transformer's keyboard!)
Q:how to construct a transformer?
Please don't! By the time you buy the special core material, the 2 types of copper wire, a good house content and life insurance for yourself, you can buy a finished and safe one from Maplin (if you are in the UK) for Pds.15.99 and that is a 45 Watt type. And finally, you say you want 60 Hz ? Then you also need 60Hz at the input, because a transformer doesn't change from 50Hz to 60Hz. Still want to know how it works? Read hyperphysics.phy-astr.gsu.edu/hba
Q:Transformers, broken, how to repair
Some of the transformer buried inside an insurance, first look at the said
Q:Question about transformers !!?
The is something wrong with your leakage reactances or the turn ratio, because N^2Lls/Llp. I'll neglect this issue. i) The total impedance of the transformer referred to the primary is Zt .03+j.1+(1.12+j6.)/16. ii) VloadVin*ZLoad/16/(Zt+ZLoad/16) ii) Same as above, except ZLoad now becomes the parallel combination of 200 and -j100.
Q:what are the properties of electrical transformers ? their uses ? their applications ?
Through magnetic induction, a transformer transfers electrical energy from one circuit to another. I think it is used to step up/down the number of volts. It also allows alternating current to transmit electrical power over long distances.
Q:The main transformer is chosen in principle
Transformer selection, you can refer to the following, but still according to the actual production needs! 1, the number of transformers to determine    (1), the number of main transformer to determine the principle is to ensure the reliability of power supply. When one of the following conditions is met, two or more transformers shall be installed.    ①, there are a lot of first-class load and although the secondary load but need to set from the security (such as fire, etc.).    ②, when the seasonal load changes greatly.    ③, when the load is large.    For large-scale hub substation, according to the specific circumstances of the project can be installed 2 to 4 main transformer.    When installing multiple transformers, it is appropriate to group the transformer according to the characteristics and changes of the load in order to flexibly switch the corresponding transformer group. Transformers should be operated in the sorted manner. Transformer low-voltage outlet of the neutral and neutral ground wire should be laid separately. For the convenience of testing, in the ground circuit, close to the transformer to do a removable connection device.    (2), the general three-level load or capacity is not too much power and lighting should be a load with only one transformer.    (3), when any of the following circumstances, can be dedicated transformer    ①, when the lighting load is large or power and lighting using a common transformer seriously affect the lighting quality and lamp life, can be set for lighting special transformer.    ②, single single-phase load is large, should be set single-phase transformer.    ③, the impact of a larger load, seriously affect the power quality, can be set for shock load special transformer.    ④, when the seasonal load (such as air conditioning equipment, etc.) about the total load of the project 1/3 and above, it is appropriate to configure a dedicated transformer.
Q:A question about Transformers URGENT?
A transformer simply changes one voltage to different voltage. There is some voltage change due to I*R in the transformer, but the transformer doesn't regulate the voltage.
Q:How is the insulation of the transformer divided?
Insulation can be divided into two parts: main insulation and vertical insulation. The main insulation is between the winding and the ground part, and the insulation between the windings.
Q:Taiwan, Taiwan, the concept of transformer
Metering points are generally placed on the two sides of the equipment for property rights demarcation point. Some "real production boundaries" are not suitable for loading tables, the measurement points can be located in the substation, if the measurement point and production to the demarcation point is different, the asset owner should bear the loss of their own property equipment. For the substation of the various routes, the measurement point is located in the various routes on the outlet. Transformer two transformers run parallel to the situation is very common. Parallel operation can make the power quality better, and better play the potential of equipment and so on.
Q:Circuit design of Flyback transformer driver.?
submit a schematic and a few concepts on the transformer. Circuits with transformers continuously have some inductive power that could desire to be dissipated whilst the transistor(s) turn off. this could reason extreme voltage spikes which could unquestionably injury a transistor (whether the case isn't warm). you may desire to guard in comparison. A 2N3055 is an quite sluggish gadget and not very proper for top velocity switching.
