- Q: Find the transformer ratio of a transformer having 350 turns on the secondary winding and 7000 turns on the primary. What RMS voltage must be applied to the primary of the transformer to develop an open-circuit secondary voltage of 63 V? if a load of 100 ohms is connected to the secondary winding what is the primary current, ignoring resistive and reactive losses in the transformer?
- Same results as Electronbut in a different way. 7000 primary turns divided by 350 secondary turns, 20:1 ratio 63 volts on secondary times ratio of 20 1260 volts on primary. 63 volts divided by 100 ohms 0.63 amps on secondary. 0.63 amps on secondary divided by ratio of 20 .0315 amps on primary.
- Q: I need this Radio Shack transformer to provide power to a HO scale model train board lighting system. This transformer will be connected to a brightness control system and then the brightness control system will be connected to building lights and street lights. I have been told this issue is a safety and Electrical Code concern?
- a acceptable web site. Face the construction south with residing house windows in basic terms in the south elevation. the north elevation could the two have a small variety of small residing house windows or be breamed with earth. For an present residing house, Geothermal is huge in case you have the money. the traditional forced warm air gadget that maximum US properties has is likely considered one of the main effective for the preliminary value and maintenance in comparison to the warmth is generates. A German business enterprise, called viessman (sp) creates very useful structures for this configuataion.
- Q: High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!
- You can consider doing transformer oil, and add noise equipment.
- Q: Transformer Transformer Principle
- The transformer is a high-pressure water (electricity); outlet is a low-pressure water (electricity)! Transform pressure is buck! Reverse can also! Pool to increase the pump Change the high pressure water! Transformers to replace the iron! Like low-pressure water sealed water tank at the bottom of the high-pressure water! Understand it! Haha! I as a lecturer?
- Q: Transformer oil filter method
- So only on-line oil treatment. Oil filters require an external oil filter and oil tank. The new oil (has been qualified, insulation pressure are qualified oil into a clean oil tank inside, the external oil filter and oil drums and transformer tubing as a whole, the external circulation of online filter oil). Mainly: 1, online filter to continuous operation, to ensure that the weather is fine air humidity less case, under the conditions of the best conditions for 214 hours of continuous operation.
- Q: Transformer is not the main and vice two coils? Resistance into which ah?
- Transformer calculates power factor If the capacity of the power transformer is denoted by S, the output active power is expressed by P, then the power factor cosa = P / S.
- Q: how are opyimy and megatron ( or w/e the f their names are)bros and hoes if they cant have roboet sex!!! if so wheres their mother and is the creator sexist about girls there is no girl robots and for that matter has some1 made a transformers porn yet.
- Females - Arcee, Nightbird, etc (and that is just from the 80s) Porn - Yes, see Rule 34
- Q: I was wondering which comic is the best read for an ongoing series about the the Transformers? It can be old or newMarvel, Dreamwave, or iDW. I was just curious because I have been a huge fan of the franchise since the first set of figures and generation 1 cartoon series but never read a single comic about them (which is actually very weird considering I am a huge comic geek) and just wanted to check one out.
- transformers are crap why do you read them?!?!?!?!?!?!
- Q: I have 2 flyback transformers one is from an old TV and the other one is from an monitor (new).I need to know the negative pin for the HV (high voltage)and the pins from the primary coil (input) and primary coil polarity. Can you tell me a method to find out these things? Thank you
- reference 1: The flyback circuit diagram calls for two sets of coils: a primary coil and a feedback coil. The turn ratio is really not that critical so usually ANY two coils in the flyback primary will work. Locate two sets of coils on the horse-shoe-like configured pins by testing the flyback pins for continuity. Often times there are more than two pins connected to a single coil in the transformer. You will need to try the different positions to see which configuration works better for your application. After you have located two independent sets of coils on your flyback, hook them up to the circuit with any polarity. If you turn on the power any you don't hear a whine or hum, try reversing the polarity (switch the leads) of ONE of the coils. If nothing now, reverse the polarity of the other coil. If nothing now, reverse the polarity on the first one you switched again. So the take home message is trial and error. Flybacks can be very picky as to coil polarity because some of them have a rectifier built in them. So try each configuration (8 of them with two sets of coils) until it whines (Occasionally I'll find one that doesn't wine but VERY rarely). Any two sets of coils in a potted flyback should work, so don't try new coils until you're sure you've exhausted all possible combinations. The high voltage will come out of the fat wire from the top of the flyback-usually connected to the CRT with a suction cup. You will not be able to locate the high voltage return pin with a multimeter. The only way to do it is to bring the high voltage line down to the pins and whichever one it arcs like mad to is the one yer looking for. Try to stay away from arcing to any of the pins used for coils. High voltage is not so good for your transistor or power supply. second reference has a lot of useful info plus photos. . .
- Q: I want to start watching Transformers Prime on TV, but I want all the backstory of just THAT universe, because i know there are MANY Transformer universes from Bay to Generation 1 to this. I just want to know what to read and watch before watching this series. Thanks!
- Transformers Prime is set in a new continuity family, launched recently by Hasbro and also includes the War for Cybertron video games. It's really complicated, but in short, you only need to know that you do not need to watch, play or read any previous Transformers material to watch this series. Even the War for Cybertron games, which are supposed to be in the same continuity family, actually clash with the events of the TV series to the point that they're effectively a separate continuity. I myself have not played the game and it's perfectly fine. Also, I've provided links for the ultimate Transformers wiki so that you can do research on whatever aspect of the Transformers universe that you want. Don't worry, the show is fine to watch from the Darkness Rising: Part 1
