Q: I am in dire need of getting a tablet within the next month (due to school work and my one hour long laptop battery life) and I was considering either getting an Ipad 2 or a Transformer Prime. I want something simple yet powerful and I don't want any hassle with navigating the tablet. I already am accustomed to using android (Having a Droid Razr and Droid 1) however I'm not sure if Android is best with getting a tablet. Please Comment!: Transformer Advantages: + Display size (10.1 inches vs 9.7 inches); + Display resolution (1280x800 vs 1024x768); + Can be like laptop with optional keyboard dock; + Rear camera (8MP vs 0.7MP); + Front camera (1.2 MP vs VGA); + Rear video (1080p vs 720p); + CPU (1.3 GHz 4-core vs 1 GHz 2-core); + RAM (1 GB vs 0.5 GB); + Ports (micro HDM, USB, SD, micro-SD vs none); + Supports Flash; iPad 2 Advantages + 3G option + Apple's legendary fit-and-finish + Larger App Store

Q: Transformer fever how to do?: ?Equivalent aging principle is the transformer in the part of the running time of the winding temperature is lower than 95 ℃ or underload, then in another part of the time can make the winding temperature higher than 95 ℃ or overload, as long as the overload time more than the life of life is equal to Transformers in the under-load time less loss of life, both offset each other, it can still maintain a normal life. ????Transformer insulation aging six degrees principle: ????When the transformer winding insulation temperature in the range of 80 ~ 130 ℃, the temperature rise of 6 ℃, the insulation aging rate will be doubled, that is, the temperature rise of 6 ℃, the insulation life is reduced by 1/2, which is insulation aging "Six Degrees".

Q: If you use a power transformer (120VAC to 12VDC) past its secondary amperage, will it burn up or will it just not supply sufficient power?: Try it and find out.

Q: What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master: This type of capacity of the transformer for the distribution transformer, that is, step-down transformer. Voltage combination to 10 / 0.4 for multi-purpose. Transformer high side current 46.19A, low side current 1154.73A. Rated capacity = 1.732 * rated voltage * rated current

Q: Two different impedance of the transformer, parallel load how to allocate?: When the impedance voltage is equal, the transformer runs side by side: Because the transformer load distribution is proportional to its rated capacity, and inversely proportional to the impedance voltage. In other words, when the transformer is running in parallel, if the impedance voltage is different, the load is not proportional to the rated capacity of the distribution, parallel transformer current and impedance voltage is inversely proportional to the II / III = UZKII / UZKII or UZKIIII = UZKIIIII, Set two transformers running side by side, the capacity of SNI, SNII, impedance voltage UZI, UZII, then the load of each transformer according to the following formula: SI = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNI / UZKI) SII = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNII / UZKII) That is, S △ I / SII = (SNI * UZKII) / (SNII * UZKI) According to the above analysis we can see: When two transformers with different impedance voltage are running side by side, the distribution load with large impedance voltage is small. When this transformer is full load, another transformer with small impedance voltage will run over load. Transformer long-term overload operation is not allowed, therefore, only the impedance of the transformer voltage overload operation, thus limiting the total output power, energy loss also increased, it can not guarantee the economic operation of the transformer. Therefore, in order to avoid the impedance voltage difference is too large, so that the parallel transformer load current distribution is uneven, affecting the transformer capacity can not be fully played, the specified impedance voltage can not be a difference of 10%.

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: About a month ago, i studied Ohm's law which said voltage is directly proportional to electric current. But today when i was studying about transformer, it said that if number of turns of the secondary coil is more than that of primary, then the induced voltage is higher than the primary voltage which was supplied and the current throught the secondary coil is less. How can this be? If voltage increases, current should also increase right? And what is the difference between emf and current?: Power stays constant on both sides. As P U*I, that means if one of either voltage or current increases, the other one must decrease. emf is basically voltage. The U R*I is also valid, but if the two coils have different number of turns, they also have different R values.

Q: Hi:I found a 10,000 WATTS STEP UP TRANSFORMER.Following are its characteristics: 1- 10,000 Watt Maximum Capacity Heavy-Duty Continuous Use Transformer. 2- Converts 110/120V upto 220/240 VoltsWhat will be its input?I means which battery or Generator i have to use for its input?Is it good idea to use that transformer to supply electricity to 1 house?: it's input is stated clearly as 110/120V, presumably 60Hz AC. You cannot use a battery to operate a transformer. If you have a generator that outputs the correct line voltage and frequency, you don't need a transformer. A transformer doesn't supply electricity, all it does is change the voltage. You are working with stuff you don't understand. You need to study basic electricity and electronics before you blow up your house.

Q: I know that someone made a transformer movie. But wouldn't DBZ the movie be a lot better!?!?!?: There are 14 official DBZ movies out to date (not counting special releases). They have been converted to English, but they are not Hollywood made. They were made by the guys who made the episodes, so they look just like the episodes. They are pretty cool. The prob is that as soon as you take Japanese animation and convert it to real lifefans tend to be disappointed in the final product. Transformers are easier to create in the visual effects department because they are machinesnot characters. However, if Hollywood does create a DBZ movie, I am sure that Goku will be able to kick the *** out of any Transformers that come at him. Btw, there are a few made that were not created by the original artiststhey suck, don't even bother watching them, you will be disappointed.

Q: 1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.: 1 - Transformers step-up or step-down voltage in a closed electrical circuit. 2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use. 3 - Allowing you to use electricity at different voltage levels for different applications.
