- Q: A CD player uses two 1.5 v batteries. If you want to plug it into a 120 v outlet, what kind of transformer will you need (Step up or Step down)? What must be the ratio of the number of turns in the primary to the number of turns in the secondary?
- Do nopt worry about transformer.just buy a charger for the CD player, it's much more than a transformer and is necessary and sufficient.
- Q: i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through
- the average transformer you see on a power line, is takin a higher voltage and is distrubing down to what your house can handle which is usually 200amps. A transformer is nothing more than copper coils wrapped around carbon metal. And on the side of the transformer there is a voltage input and output tag. Transformer are huge and small. I work with them everyday.
- Q: if i take a small transformer meant to be used at 120v:9v 60hz, and discharge a 360v 100uf capacitor (or similar) into the 9v winding, will i get a high voltage pulse on the 120v winding?
- Only at UF(which I am a proud student). I suppose you would as you have at that instant a rapidly changing magnetic field in the secondary winding, but it might occur so quickly or so violently that it may be un-noticable.
- Q: I don't know how this conversation started today, but a couple of my friends asked me who would win in a battle Voltron or the Transformers. They did not specify which version of Voltron or which group of transformers. Give me a scenario and tell me what you think!
- Transformers.
- Q: the use of autotransformers is strictly prohibited.
- The double-winding type safety isolating transformer has two windings which are input (primary) windings and output (secondary) windings, and the two windings are insulated from each other, only by magnetic connection, that is, secondary Winding and the earth does not constitute a loop, if the use of additional insulation appliances, you should use a safe isolation transformer. And since the lotus transformer all of its winding are connected, by sliding the position of the contact to change the size of the voltage. Therefore, the autotransformer primary winding (power circuit) and the secondary winding (power supply circuit) is not only between the magnetic connection, as well as the direct connection of the circuit. It and the earth constitute a loop, so it can not be used as a safe voltage power supply. Therefore, the safety regulations: lighting transformers must use double-winding type safety isolation transformer, prohibit the use of autotransformers.
- Q: A step up transformer has 5,000 turns in the secondary coil and 200 turns in the primary coil. The primary is supplied with alternating current with an effective voltage of 900V. (A) What is the voltage in the secondary coil? (B) If the current in the secondary coil is 20A, what current flows in the primary coil? (C) What power is developed in the primary coil? (D) What power is developed in the secondary coil?
- a) (5,000/200) x 900V 22,500V. (5,000/200) 25:1. b) (20 x 25) 500A. c) (900 x 500) 450,000W. (22,500 x 20) 450,000W. (450KW). Both must be the same, if no losses.
- Q: I am learning about transformers and one of the items to calculate is the impedance. I need to calculate regular 60 Hz Core and Coil Shell Type Transformers Al wire in secundary, Cu Wire primary and use Epoxy paper for insulation.
- It's pretty difficult to calculate the impedances (there's more than one) entirely from the transformer's design data. It's easier and more usual to decide on an equivalent circuit (there are plenty available depending on how well you want to model the transformer) and then to determine the parameters by a mix of calculation and measurement. A pretty basic equivalent circuit which refers all impedances to the primary side, has the primary terminals connected first by Xm and Rc in parallel (the magnetising reactance and core loss resistance) and then by a third parallel branch containg a series connection of leakage reactance Xl, winding resistance Rw and an ideal transformer of turns ratio Np/Ns. Xm is best obtained from an open circuit test but could be calculated as the inductance of the primary winding. For the latter you'd need to know core dimensions, number of winding turns and the magnetising characteristic of the core iron. If you have conductor sizes and conductivities you can calculate the winding resistance Rw, referring the secondary part to the primary by multiplying it by (Np/Ns)?. You can deduce Rc from the losses measured on open circuit at nominal voltage and Rw from dc resistance measurements on the windings. If you know the specific hysteresis and eddy current losses of the core material, you can also have a good stab at calculating Rc. The leakage reactance is quite difficult to calculate from first principles - even designers usually resort to some empirical factors. Basically it's determined from the short circiut test which is at nominal secondary current. The ratio of primary volts to secondary surrent (referred of course) on secondary short circuit will get you close to Xl - you can adjust for Rw which can be determined from the losses on short circuit (core losses are absent here!) or by the two methods indicated above. It's normally Xl that's referred to as the transformer reactance and together with Rc and Rw, the impedance.
- Q: How to measure check the good transformer ?kindly if anyone might upload the video for me . in this regarddo we have to take it out of the board ? (isolate from other components) .what to check . what should be the values ?when checking , supply should keep on or not ?any website that explain these things and upload the videos in these kind of matters . I want to learn the repairing and maintenance of electronic electrical devices instruments of daily use ?thanksGOD BLESS YOU ALL
- A quick-and-dirty check is to measure the resistance of the windings. There is no correct value because every transformer is different. For a mains step-down transformer normally the primary windings will be 50 ohms and the secondaries will be a few ohms. If there are double windings (like 0-115 0-115 on the primaries) then both windings should have a similar resistance. This is not a guarantee of a good transformer because it will not detect shorted turns. The only way to detect that is to take the transformer out, power it and measure the output voltages.
- Q: i was just wondering, i've never really watched transformers growing up except for a few episodes and beast wars, but not enough to know whats going on. my question is, from the movie transformers and transformers 2 revenge of the fallen, how much does both movies follow the original series and what changes have been made? thanks [:
- It does not follow it at all.
- Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.
- The voltage is transformed up to thousands of volts and low current for minimum heat loss in the wires. Then down to low voltage at high current to the neighbor hood.
