Q: High school physics, according to the transformer U1 / U2 = N1 / N2 Can make a large voltage into a small voltage, but the small voltage can become a large voltage? Need no conditions? Can the transformer be used only for alternating current? I am now only high school physical level, answer not too esoteric or too professional! Thank you !!: Small voltage can become large voltage. If only in the theoretical considerations, as long as meet the N1 <N2, you can make U1 <U2.

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: I want my car to be a transformer: My Penis Transforms!

Q: 440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.: 440vAC is less danger comparing to 11,000vAC which arcs easily than 440vAC but both are very dangerous. Lower volttage will not break the insulation easily. Higher the voltage (500v ) means maintain higher distance otherwise it will develop arcing. The electrical shock and burning is proportional to the SQUARE of the VOLTAGE even the current is very low. 16v thru heart is fatal to humens , above 32v AC is said to be lethal .

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?: Ohm's regulation, the place it applies, will consistently artwork. the significant factor is the place it applies. on your case, the present is decreased via a million/20 interior the secondary whilst in comparison with the present interior the regularly occurring. however the fee of the secondary present day might nicely be calculated via making use of ohms regulation in case you have a resistor load. case in point, in case you have a one hundred volts utilized to the regularly occurring, then the secondary is 2000 volts. in case you have a a million M? load, the secondary present day is 2000/1M 2 mA. meaning the regularly occurring present day is 20 x 2mA 4 hundred mA. in case you alter the burden to 100k?, then the secondary present day is 20 mA and the regularly occurring present day is 4 amps.

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.: A welding transformer is generally a Step-Down transformer with variable secondary taps and very high secondary current rating (on the order of hundreds of amps) that will drive through what's essentially a shorted secondary without translating that back to the primary and tripping the supply side breaker. The frame and windings are designed to withstand large magnetic forces produced by the high current impulses. They're designed to withstand a lot of heat for short periods of time, and are almost always air cooled. Welding transormers are generally physically sized so they can be moved easily. Power transformers as a group adjust line voltage depending on the application. They are designed to continuously handle high voltages (thousands of volts) and large amounts of current that doesn't vary much over short periods of time. In commercial and utility applications they are oil cooled. Most power transmission transformers are very large.

Q: i have the 240V AC to 12V AC step down transformerwhen i connecting directly to 240V line the output is higher at about 16Vi need only 12V for my circuithow to get the exact amount of output voltage?: Put a load on its output to reduce the peak voltage. Try 60 ohm resistor rated 5W. If not lower down into 12V, then try 24 ohm rated 10W.

Q: design a quarter wave transformer to match a 73 ohms antenna to 300 ohms transmission line fed by a 100MHz FM radio station: Transformer impedance required: sqrt (73 x 300) 147.986 (say 148) ohms. The 1/4 wavelength in air is (75/100) 0.75 metres. You have not stated what you are using for the transformer, so you will need to allow for its velocity factor. But the transformer could be 0.75 metres of parallel rod spaced as required for the impedance. I am also assuming the antenna is balanced (sounds like a folded dipole).

Q: Guys can you tell me that how can I calculate transformer winding?Example:- I need (12volts, 4Amps, 50Hz on Secondary's side of transformer and give 230volts 50Hz on Primary's side of transformer) how I calculate the wire's number of turns? In this case I can give different values of current like 1Amp, 2Amps, 3Amps etc on Primary's side of transformer. But I need constant 12volts, 4Amps, 50Hz on secondary. So how can I calculate.Please give an answer with an example basis on (0-12) transformer.: Basically, the ratio of voltages is the same as the ratio of turns. The currents are the inverse ratio but that kind of takes care of itself if you just deal with the voltage ratio.

Q: I am re-winding transformers, and I was wondering if braided copper wire can be used for the secondary winding. I will be using large gauge wire (4-8 ga.) and I just need to know if the performance will be terrible if I do use it.: I assume that you are talking about stranded wire with plastic insulation. The strands are not actually braided, but only twisted together. There is such a thing as braided wire, but it is a special product for high frequency. The plastic insulation, usually polyvinyl chloride (PVC) will likely get too hot in a transformer. The stranded wire with PVC insulation is also much thicker than magnet wire of equal copper size. The number of turns that will fit will be greatly reduced. You can probably not successfully strip of the PVC and put on a varnish type insulation. If you wind the transformer with PVC insulated wire, the number of turns that will fit will limit the available volt-amperes to some extent and you may need to limit the load even more because the safe temperature of the PVC insulated wire is much lower than the safe temperature of magnet wire. Edit 1 Duty cycle is certainly an important factor affecting operating temperature. That could allow PVC wire to work. There still might be a problem with getting enough turns in the space available. You might consider going to a motor rewind shop to see if they will sell a small amount of magnet wire of the proper size. If you have cheap PVC, try that first and estimate how many turns you need if you need more. Magnet wire can safely run hotter, so smaller gage wire can be used. You could also see if recycle places will sell recycled magnet wire. If you can get magnet wire somewhere near large enough, you could use two or three strands in parallel.
