Q: Find the transformer ratio of a transformer having 350 turns on the secondary winding and 7000 turns on the primary. What RMS voltage must be applied to the primary of the transformer to develop an open-circuit secondary voltage of 63 V? if a load of 100 ohms is connected to the secondary winding what is the primary current, ignoring resistive and reactive losses in the transformer?: Primary/secondary ratio 7000/350 20/1 For 63 V on secondary: Primary volts 20 * 63 1260 V.

Q: i need to have an immediate answer (solution to this) thanks:Determine the transformer bridge rectifier and filter capacitorspecifications/values required to produced an output current of 3A and a nominaloutput voltage of 17VDC with a ripple voltage of 2 Vpp. Assume a line voltage(from Meralco) of 220VAC, and that the design is to use a center-tappedtransformer.2. Given the characteristics of the raw DC supply just designed, determine thecomponent values of a transistor regulator circuit (based on “Simple TransistorVoltage Regulator Circuit” from the CCS1: If you are to use a center-tapped transformer, you don't need a bridge rectifier; a pair of diodes will do the job. The output voltage will need to be about 13.5 vrms each side of the center tap; this will deliver 19 volts p-p, the rectifier will eat 0.75 volts, the ripple will amount to one more, and you'll have your 17 vDC. Since the filter capacitor will be working into a load of 17/3 ohms, and the voltage decay is to be no more than 2/17 of the output, you can use the exponential decay equation to figure the necessary time constant, and use the load resistance to get the capacitance. (You can punch a calculator as well as I can.) 2: The regulator transistor will be burning five volts at three amps, or 15 watts dissipation. A TO-3 may be satisfactory in this application, but it will be a close call. The rest of the component values can be determined using Ohm's law.

Q: hey Guys. I'm a big fan of Transformer movies. can't wait to see the Transformers-2. Not a real trailer has been released? :( . I would like to know which robots r going to b in the next epic battle?? :): Soundwave. Optimus Prime 3

Q: A 2200/220V, single phase transformer has the following resistance and leakage reactance referred to primary: R5.6 ohms, X22 ohms1. calculate V2, I2 and cos(2) when the primary is supplied with 2200V, 9A at a lagging power factor of 0.8. Neglect Io.: you may get the comparable voltage out of one output as in case you had related all 3. the different 2 might have decrease voltages for the period of them. case in point, say the transformer replace into regularly a 240 to 480 3-section delta. in case you have been to place 240 for the period of legs A and B, you may get 480 for the period of A and B of the output. i've got self assurance the B/C and C/A outputs might have 240 each and each, because of the fact the unconnected C section might seem as a midsection-faucet to the A and B legs

Q: I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the yahoo answers community.: Transformers consist of a primary and secondary winding. If you are certain of the AC input side (and the fact that they are black and white suggest you are) then the green and red wires are the secondary and would produce the 7.5kv AC output. Neither of these wires can be connected to ground as that would short the transformer and more than likely fry it,trip a circuit breaker , cause a fire or all three. Secondary windings with more than two connecting wires would indicate a transformer that can be tapped, which means that various voltages can be obtained depending on the combination of the output wires. 7.5 KV is a very dangerous output and if you are using the transformer outside of it's intended device, a fuse on one of the AC leads would be an absolute necessity.

Q: I am a transformer factory salesman, the company let go to the field to run business, if you go to a strange city, where the main starting from where the few places, and which units to contact? If the local sales in the transformer factory, then work well to carry out? What are the sales channels?: 1. Power supply company tender 2. Cabinet manufacturers 3, the installation company 4, direct customers, to the planning bureau to find, in advance to know which new project 5, design institute, know some late 6. Power supply company front desk, people come to install more late

Q: If I have a step down transformer, the voltage in the second coil decreases. From conservation of energy (Power of firstpower of second coil) the powers are equal. But if PU*I and the voltage decreases, does the second coil have a higher current in order to maintain its power?: A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages. It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa. hyperphysics.phy-astr.gsu.edu/hba Goodbye

Q: I want to make presentation about transformers, I need to know suitable definition.I also want to know the Major Components, and Protection devices.Thanks a lot: It is about the heroic Autobots and the evil Decepticons, two factions of alien robots who can disguise themselves by transforming into everyday machinery. The Decepticons desire control of the AllSpark, the object that created their robotic race, with the intention of using it to build an army by giving life to the machines of Earth. They also have lasors and shields. Some also have machine guns and others have swords.

Q: I have a Whirlwind microphone splitter box with a direct out and a transformer isolated output. What's the reason for the transformer isolated output?: Microphone Splitter Box

Q: Transformer stop power operation, the neutral point must be grounded: (3). When the transformer between the high and low voltage coil capacitive coupling, the low side of the voltage will reach the resonance conditions, there may be resonance over voltage, damage insulation. For the low voltage side of the power supply transformer: (1). Since the low side of the power supply, in the system into the system before the high side of the transformer single-phase ground, if the neutral point is not grounded, the neutral point of ground voltage will rise to phase voltage, which may damage the transformer insulation; (2). In the case of non-full phase incorporation, when the phase of the generator is connected with the system, the neutral point of the transformer is not grounded due to the frequency of the generator and the system. Will be twice the phase voltage, the other phase (ie, unphaseed) voltage up to 2.73 times the phase voltage, will cause insulation damage accident.
