i have a transformer and i dont know anything about it. can someone help me with it.ps: i dont know how many turn the transformer have. dont the voltage either
Transformers are used to increase/decrease Voltage and current depending on your requirements.Don;t forget whatever power you put in only will come out, so if you Impress x Voltage, and y Current across a transformer, it either increases voltage, while reducing current, or vice versa, since Power Voltage × Current, therefore, if you are going to increase current, output voltage reduces, and if you increase Voltage, output Current reduces.Here is a transformer picture google .in/images?um1hlenbiw1280bih663tbsisch:1sa1qelectrical+transformer+diagramaq0aqig7aqloqelectrical+transformer+gs_rfai If you follow this link, you will see a picture of a few transformers, with two windings, and is called a two phase Transformer. There are in general two types of transformers, Step up and Step down Transformers. Step up ones have little primary winding( The winding where you put in you power) compared to secondary windings(The output ).Since electricity has magnetic properties, it starts to Induce the other side, since it has more windings, more Voltage is induced, and since input power output power, if Voltage increases, output current reduces. ex.Input Voltage10V, Electrons that flow 10Amperes Ratio of Primary to secondary Winding 1:2 Output power 20V, Electrons that flow 5Amperes 10 into 10 20 into 5 This is a rough example to explain. There are numerous other factors that are needed to calculate Transformers, such as Impedance, Frequency of Alternating Current, Flux losses, Materials used to laminate the iron core, or any core, and so on. Hope I have helped
You can tell roughly how much power it can handle by the size and weight. Old style power adapters (transformer types heavy), like you plug into the wall, provide 5-10 watts or so and weigh 4-10 ounces. If it is really small it would be a signal level transformer and be in the milliwatt range. The voltage is somewhat irrelevant except to the output. Most transformers will take hundreds of volts before the insulation breaks down. What you can do is find a current limited 10VAC (or so) power source and place it on one side of the transformer. Measure the other side and you will discover the ratio. 30VAC would be a 1:3, 3.3VAC would also be 1:3 but your source would be hooked to the large winding. If you don't know much about electronics, stay away from hooking anything to a wall outlet, the current there is a couple hundred times a lethal dose. Keep your mistakes to letting the smoke out a a few low cost devices. A small wall outlet transformer is a safe way to experiment as the line voltage is isolated and all the shock you can get is limited to the secondary or output of the transformer.
_IF_ the toroid replaced into under pressure out to function off 50-60 Hz, and you are able to grant a prevalent transformer which will grant a similar AC output (the two voltage and modern means), then it is going to artwork. even nonetheless, if that toroid is a factor of a switching ability grant, then a prevalent transformer won't artwork. So the question maintains to be, is there an number of digital factors under pressure out around this toroid? if so, then you somewhat could desire to acquire a sparkling toroid, or in case you have a large style of time on your palms, rewire the prevailing one. (diploma and eliminate latest twine, noting their association and counting the turns as you circulate). If the toroid is meant to artwork on 50-60 Hz, then you somewhat ought to have some situation getting a prevalent transformer to greater healthy interior the lamp, yet i think you are able to make it exterior and placed it into this is very own container, equivalent to a modular grant.
