- Q: During the trailers before the movie transformers, there was a trailer for a movie that looked like it was done by an amateur video.It didnt have a name but it had the statue of liberty flying through the streets.Anybody know the movie or wat the movie is about?
- Yes. okorder
- 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?
- try okorder
- Q: I remember playing with a brand of shapeshifting car/robot toys in the 80's when I was a kid that was not Transformers. They were popular, had a catchy commercial jingle, and were NOT Transformers, but I can't remember what they were called. Help!
- That would be GoBots.
- Q: Design a control circuit to step-up/step-down the voltage either in primary or secondary side of the transformer. The tapping (step-up/step-down) of the transformer must be auto controlled by VB program.For example, suppose if the desire voltage in the secondary of the transformer is 15V, but because of the loss, the voltage might drop to 12V. So, a sensor is used to detect this drop and send the message to VB. VB will process the message and send the reply signal to control circuit so that the voltage will step up (compensated) to 15 V. If the voltage exceeds 15 V, VB has to rectify it also.Can anyone please show me some guidances or circuit diagram of this project? Thank you!!!!
- Thank okorder
- Q: I will be living in Germany for a while and I'm trying to plug my TV in, as well as one or two other things. The 1000 transformer I have works, but whenever I plug in the power strip to plug in more things than just the tv, it will automatically blow the power in the house and I have to go flip the switch again. Other Americans I know here in Germany do not have this same problem. I need help!
- Hi, The 1000 transformer the is mentioned is not too clear. However, since transformers are rated in power like watts in small designs and volt/amps as they are larger, I will tend to feel that the transformer you are using is a 1000 watt unit. If it is so, then that 1000 watts is the total power it can transform. A thousand watts is not a large quantity when it comes to televisions and other modern electronic equipment. Depending on the size of the television, that alone can use up the power of the transformer. The transformer would have been protected with a suitable fuse or breaker to prevent overloading by the users. Hence the breaker will trip on overload to protect the transformer. Check the power consumption of the appliances that you want to use.
- Q: I want to make a simple flyback transformer driver. I have a flyback transformer of samsung CRT monitor. Can anyone give me a complete design of flyback transformer's pin. What are the required components. Please give answer in detail.
- These transformers are designed for TV or monitor line frequency. They use a square wave drive at the line frequency (15625Hz or more for a monitor) The on time is around half the duration of a cycle or more, so 32us for 15625Hz. The driver is a switch, it is on for this time. The current builds as a sawtooth (ramping) current in the inductance of the winding during this time. The design of the driver switch needs to take into account ratings are in the safe operating area (SOA). This means the rate of change of voltage and current, as well as the instantaneous V * I must always be within ratings. It means that the switch should be rapid, so there is minimal time spent in the transition off to on and on to off. There usually needs to be a snubber network to control voltages across the transistor. The pin connections of the transformer? The links below show how to do it basically. It also shows how to check out and identify the windings you need, and also to verify them, using the schematic of the original device if possible. Tracing wires on the circuit board can help too, to identify the primary. You only need to identify 4 pins usually. There are some safety issues here. Some have small internal capacitors that store energy. This can give an unpleasant shock. It could be around 0.2 joules or more because of the high voltage. I am not sure what sort of a hazard this might be, but I wouldn't take it too lightly or use it to shock yourself or others. I assume you are using a 12V DC supply @ a few amps current to power this.
- Q: Transformer and the middle of what is the difference
- Often referred to as the transformer is the frequency transformer, is used to change the size of the AC voltage electrical equipment. It is based on the principle of electromagnetic induction, with the same frequency, between two or more windings, the exchange of AC voltage and current to transmit electrical energy of the static electrical equipment. In the week is the IF transformer or inductance coil, is a fixed resonant circuit with a transformer, the resonant circuit can be fine-tuning within a certain range, so that access to the circuit can achieve a stable resonant frequency. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
- Q: I would like to get my grandchild all the transformer movie dvds but don't know the names of all of them. please help and thanks
- Wow that's the best gift you could give ! I would be thrilled to get that ( and I'm a teenager, LOL ). Someone already took my answer. :( But yeah I'll repeat it anyways: Transformers, Transformers: Revenge of the Fallen, and Transformers: Dark of the Moon ( BTW I heard it comes out November 15th, not September 30th, I'd get that checked out ). What a lucky grandchild, I'm buying them all on blue-ray when the third one comes out : If he has a game station (xbox 360 or ps3) why not get him the games? :p too much? okay nvm.hope I helped
- Q: I need a transformer that can produce 10 volts from a 1/2 volt change in the primary winding, but don't know how they are classified. The transformers I've seen on the internet give no clue of the winding ratio, just a serial number. Thanks.
- Your question makes little sense as listed. Transformers are not usually used to amplify 1/2 volt variation. We need more detail.
- Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.
- The voltage is transformed up to thousands of volts and low current for minimum heat loss in the wires. Then down to low voltage at high current to the neighbor hood.
