Q: A transformer has a 100-turn primary coil and 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary os connected to an electrical devic with a resistance of 1000 ohms.what will the voltage output of the secondary be?what current flows in the secondary circuit?what is the power in the seconday coil?what is the power in the primary coil ?what is the current drawn by the primary coil?: A Step up transformer is exterior a ability station and will develop the voltage for the flexibility lines so it may flow swifter and extra effective parts. A step down transformer is after the flexibility lines to lessen the voltage and making it secure for domicile use.

Q: I have two questions:1. Can somebody please explain to me how transformer coupling is so good for maximum power transfer? Please be thorough. Is it because of the primary ac resistance and bjt output impedance being equal? I mean this should work because the power on the primary coil is the same as the power on the secondary coil so the power delivered to the primary coil which is the maximum power in this case, would ideally be delivered to the secondary coil, right? 2. And how can transformers be used to increase the overall voltage gain of a two stage common emitter based amplifier, something like: 1) Its basically impedance matching: the relatively high output impedance of the first stage can be matched to the much lower Hie input impedance of the second stage. Also any attenuation caused by the shunt resistance of the bias resistors working against the output impedance of the first stage (as shown in the R-C C coupled figure for question 2) can be eliminated by applying the bias network voltage at the low side of the transformer secondary, with that point bypassed with a capacitor to provide a good ac ground 2) Replace the 4K collector resistor with the transformer primary winding, eliminate the capacitor C3, connect the high side of the secondary directly to the base of Q2, connect the junction of R1 R2 to the low side of the secondary and add a capacitor from that point to ground to provide adequate low impedance at the lowest frequency of interest. Transformer coupling is efficient, but bandwidth is limited by the transformer, and the overall gain will vary with individual transistors. Both of these warts can be improved by applying negative feedback from the output back to the input stage.

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?: The product of voltage and current should be equal,both in input and output less conversions loss.

Q: Are you agree with me that Transformers The Movie (1986-Cartoon) is better than Transformers (2007) in terms of it's storyline, dramatic and character's behaviour?Transformers (2007) is such a great movie but i think i prefer 1986's cartoon. I always make me want to cry.: I'v neva seen the cartoons but the movie is brilliant(Josh Duhamel is sssssooooooooo hhhhooootttt!!!!)

Q: The core part of the transformer is composed of sub-and sub-components, which are generally divided into two transformers. Urgent, quick answer What is the core part of the "what" and "what" sub-composition ah? The "What" son, this "what" is to fill you ah.: The core part of the transformer is the transformer is the exchange of AC voltage, current and impedance of the device, when the primary coil with AC current, the core (or core) will produce AC flux, the secondary coil induced voltage ( Or current). Sort by cooling: dry (self-cooling) transformers, oil immersion (self-cooling) transformers, fluoride (evaporative cooling) transformers. According to moisture-proof classification: open-type transformers, potting transformers, sealed transformers. According to the core or coil structure classification: core transformer (insert core, C core, ferrite core), shell transformer (insert core, C core, ferrite core), Ring transformers, metal foil transformers. According to the number of power supply categories: single-phase transformers, three-phase transformers, multi-phase transformers. By use classification: power transformers, voltage transformers, audio transformers, IF transformers, high-frequency transformers, pulse transformers.

Q: hi , i got some electronics frm asia( like camera and hair dryer) , which can only be used in 220 volts. which converter or transformer sud i use which changes 110 volt to 220 volt ? and where can i get it ? i searched for it . but i found converters that change 220 v to 110 volt :(: Check Hammond, they have auto transformers that can be wired either step down or step up. You need to know the total wattage of the devices you have , and choose the largest one. Frequency, hopefully, is not an issue here.

Q: I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?: SQUEEK? That sounds like a high (audio) frequency oscillator. So this sounds like a pulsed regulator, not like a transformer-type power supply. I would guess that your unit is measuring the battery voltage, then applying a pulse of power to charge the battery, then checking the voltage again in a continuous sequence. This would be a switching type charger. 5 Volts - sounds like a personal electronics unit, for instance a cell phone or personal entertainment. Right? 240 Volts - Sounds like Europe. Right? (In America it would either be 120 Volts or some switching supplies are designed to operate from 90 to 250 Volts.)

Q: i have fuses and everything that i can use to test my primary but should i add more turns on the primary side? yes i know line voltage is dangerous. yes i have worked with it before and know how to work around it.: More information needed. I guess you are in the USA with 115 volts AC and 60Hz. For a given size (cross section) of core and mains frequency there is a turns per volt although special alloys like Radiometal upset things as everything gets to be about twice as powerful as standard transformer iron. If you can thread a few turns through the core you will be able to measure the voltage and thereby deduce the turns-per-volt. I 'd suggest that you leave the primary as it is and just rewind the secondary. As to your flyback circuit, you would probably be better off making a fixed frequency oscillator (555 timer?) and using it to drive the power stage. As to wire size on coils, a very old rule of thumb used to be 2000 amps per square inch of copper. 5 amps therefore needs 1/400th of a square inch. Possibly you may end up with more than one wire size that will suit. Mullard used to do some excellent designers guides books in the 1960s but unfortunately I can't put my hand on them at the moment. Good luck!

Q: Will the 250KVA, 500KVA, 630KVA Van transformer size,: Box transformer inside the configuration is not the same, the size will be different, which factory production size is not the same

Q: i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?: my take was, if you're a decepticon, why give away anything until you're ready to strike? think about it, you're an a**kicking supercomputer with crazy weapons and you can hack the sh** out of the most sophisticated systems on this planet in a matter of seconds. you're looking for a seemingly insignificant pair of glasses WHICH ARE FOR SALE ON E-BAY. you can't just hack a bank or large corporation, jack a few million, and give the high school junior a huge amount of money for the glasses and just wait a day for UPS, THEN go for Megatron and the All-Spark? that was the big one for me, also they put too much comic relief on the transformers side. that version of soundwave they put in there was way too cutesy. and sorry dude, but Meghan Fox is just Jennifer Connolly ten years ago, but without the great skin. don't get me wrong, i thought the movie was decent enough, but people are going crazy over it, and it's unwarranted. that's all i'm saying.
