Q: How can we figure out which side of transformer is primary which one is secondary by measuring resistance ? I know that the side where input or supply is provided called primary from where the output is collected is called secondary side in both step-up step down transformersAnd, how can we troubleshoot a bad or a good transformer by measuring its resistance on both sides i.e. primary side secondary side ?thanks: I was wondering the same thing myself today

Q: Transformer Transformer Principle: Transformers rely on two coils to transform. Principle is in the case of loss without loss according to the input power = output power, that is, P1 = U1 * I1 = U2 * I2 = P2 to change the pressure, specifically in high school physics textbooks, I now basically forget

Q: I need to know how and auto transformer works and how i can get 240 with it thanks in advance and if theres a website thats explains transformers that would be great (: thnx again !!: Auto transformer is a single coil wound on a core(iron/ferrite) having three terminals. Out of three, two terminals are fixed on each side. But central terminal is provided in such a manner which can move on the coil from one side to another side. Voltage input is fed across two ends, and output is taken across central point and ground point. Accordingly one end/ common end/ becomes common to both input and output. In some cases, top (phase) terminal, winding is continued further to a tertiary point left open, and variable point moves up to this tertiary point then, in auto transformer only, step up of output is achieved. Please note that input and output voltages can not be isolated in auto transformer. However we same some money since same winding is used common to primary and secondary.

Q: hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated: Solder the joints!!!!It is OK to use the old connectors!!!! Be sure that the power of the new transformer it is the same with the power of the old one.

Q: i have read different forums explaining what really is an isolation transformer but unfortunately i am having trouble on grasping the main idea? please help, why do they say that isolation transformer can help a person being electrocuted even if he touches one of the secondary terminals??? how is that??? thank you: AC line voltage has one wire (neutral) grounded and the other hot. Touching the hot lead is dangerous, as your body can have a path to ground via various means. The isolation transformer removes that grounded neutral connection, so touching the hot lead on the output of that transformer is not dangerous as there is no path for the current to flow in. You have to make contact with both of the two leads to be a hazard, to provide a current path.

Q: Maintenance of a household table lamp, found inside the 220v AC to 12v DC, (with a 12v mirror headlight) Transformer has red, blue, black three into the line, plus or minus two output. Ask why is the three lines? In addition to the line of fire and the zero line, what is the remaining root?: You see how it is connected to the law ah ~ which is connected to the power supply is the power cord ah ~ may also be the designer in order to be able to work at 220 and 110 (some countries are 110) and designed. Why did he do so?

Q: i have an epcos 565-2 transformer and i want to know how much it will raise the electrical output of a standard 1.5 volt battery. i really do not know much about transformers, but i bought a motor, assuming that i would be able to do fun things with it, and i hooked it up to all the power i could(solar batteries, and numerous amounts of AA batteries) but it wouldn't spin anything that i attached to it more than probably 60 rpm. i bought a transformer to boost the power, and spin the motor much faster. the motor is graded for 3000 rpm maximum, but i just want it to be above 250. any help would be appreciated.: cule is totally wrong. Transformers only work with AC, not DC But even with AC, transformers do not boost power, they only boost voltage, with a lower current. Use more batteries, such as several 9 volt batteries

Q: Do not all change the pressure? What is the difference?: Transformer is the same frequency of a voltage into another level of voltage, such as the (frequency 50hz) 10kv into (power frequency 50hz) 400v. The inverter can convert DC into any frequency (there are many types of inverter, the output voltage frequency range is different) AC but the voltage level will not change.

Q: i m studying about the non linearity in systems and transformer is non linear in nature: You will drive the core flux well into the saturation region with a disproportionate increase in iron losses. The magnetising current (which is normally very small) will also increase strongly and disproportionately. The transformer might still function quite well (although with higher harmonic content in the voltage) but especially due to the high iron loss and also because of the increased magnetising current you would have to reduce its rating quite considerably. These are the effects of non-linearity. The higher voltage you would be applying would also place all the transformer insulation under a higher stress, increasing the risk of an internal short or external flashover. You would in minimum have to subject the transformer to a suitably elevated over-voltage test, which it probably wouldn't withstand. This sounds like quite a big transformer and if there is any danger to persons or to neighbouring installations if an accident (explosion, oil spill or fire) were to occur, you, or the responsible person, could easily be facing a negligence or even gross negligence charge for authorising the change!! I definitely wouldn't sign off on that one!!

Q: Is the transformer a power adapter?: No, the transformer should be a device that performs impedance matching in order to achieve maximum power transmission. In turn, "power adapter is a transformer" is also unsatisfactory, at least the general power adapter contains a transformer. As a power adapter requires a common power supply into a device required power, voltage, current, impedance and other aspects of the match, of course, it needs a transformer. Since it has the function of changing the voltage, call it "transformer" is no harm. I would like to say that the power adapter is not only transformer, it needs to achieve in addition to the voltage other than the parameters of the match, for example, the most simple general-purpose DC adapter in addition to transformer that there is a "rectification" process. The transformer, narrow sense that it is just a component only, like resistors, capacitors, transistors and so on.
