- Q:Power transformer primary current and secondary current
- Do not know what the specific content of the question you ask? If the relationship between the variable and the ratio, then the secondary current and primary current ratio of the transformer for a second and second turns ratio, the need for specific problems.
- Q:I know that Cartoon Network showed a couple of commercials for season two of Transformers Animated,but when?To add,the stopped showing those commercials.like,one week after the first time the commercial aired.Did the have second thoughts and decided to cancel it?
- Transformers Animated has been cancelled after the end of Season 3. This was announced at BotCon approximately two weeks ago. Currently, there has been no announcement as to what will follow it in the Transformers TV line, other than that there will be something.
- Q:For my proposed new aluminium extrusion factory I ve the load of 250 kw heater and 670 HP of motors.Whats the kva rating of the transformer I should go for?Pls advice.
- The total load is around 750kW but allowing for low power factor on the motors I would suggest you make it 1000kVA' get that or the next size up transformer off the shelf. Fit automatic power factor correction to reduce the load and save money.
- Q:I need to make a small transformer (that uses AC obviously) that would boost an input voltage of 20-30 millivolts at 1.5 mA to a output voltage of 1 volt (with a current that would obviously be very small) How must I design and build the transformer to accomplish this? Thank you.
- Transformers follow Ohm's Law and multiply or divide voltages based on the number of turns making each coil. You need only ensure your two coils have the appropriate number of windings. As for actual numbers for the windings, 1.5mA is an absolutely tiny amount of current, so you have considerable flexibility in this. If you are looking to build a transformer, you should look up the information on what you're planning to use for a core, to be able to calculate the voltage across the secondary coil.
- Q:(1) A Step Up transformer steps up voltage.(2) Voltage is directly proportional to Power.Conclusion: A Step Up transformer has the capacity to increase Power.Contradiction: By First Law of Thermodynamics, Energy can neither be created nor be destroyed. Hence No one can create energy out of thin air like, that of by just using a Step Up transformer to increase voltage and hence power.Where is the whole theory wrong?
- P I*V A step up transformer DOES increase output voltage BUT it also lowers output current. So it's incorrect to say that Voltage is directly proportional to Power. Voltage is Power divided by the Current. If the output voltage doubles, output current drops by a factor of 2. This way, total output power stays the same as input power, and all laws of Thermodynamics are satisfied. P_in I_in * V_in I_out * V_out P_out
- Q:The specific steps and procedures for installing the transformer
- Hello, you said it should be the frequency transformer installation steps it. Steps are as follows: first equipped with skeleton Oh, and then use the winding machine around the enameled wire, and then add the fuse (if the customer specified to), then dip tin, dip tin is the dressing, the package is finished shake the film, shake the film is Plus shell, such a transformer to do a good job. I hope I can help you.
- Q:I understand that a 70-volt transformer is used in a commercial environment, to connect several 70-volt speakers to a 70-volt amplifier. But why does a 70-volt transformer have all of those different colored wires coming from it? What do they connect to, and what are they for? How would I connect a 70-volt transformer to an amplifier, and where I connect the cable that goes to the speakers? Please explain this to me in an easy to understand way, because I was curious about this for a long time.
- Briefly, the reason for the multiple wires is so that a given transformer provides the option to select any of a variety of output watts, depending on its application. In other words, instead of a system installer having 1/2W transformers for classrooms, 1/16W transformers for tiny study rooms, and 2W transformers for hallway speakers, they use mostly ONE type of transformer for the majority of the installation, and select appropriate “tap” settings for each speaker's application. These selection possibilities may or may not be marked on the transformer, however! I used to use transformers that had center-tapped dual primaries that could be connected either in various series or parallel combinations, providing a whole range of wattage possibilities. This was done by looking at the spec. sheet and using any of 8 or so different wattage hook-ups by interconnecting the appropriately colored wires. Not all were used, depending on the desired wattage. There were NO markings on the transformer itself, other than the part number! I don't know your situation (or your transformer), but in general: The 70-volt line output covers the distance to the transformer-plus-speaker location, the transformer wire taps are selected for the desired output wattage to the selected speaker, and the sum of all the speaker wattages must be less than that of the amplifier rating. However, knowing the matching transformer's capability and wattage selection scheme is a key element. With luck, the secondary is marked for the speaker impedance (“common”, 4-ohm, 8-ohm, etc.) and the primary is marked for wattage (“common”, 1/4W, 1/2W, 1W, 2W, 5W, etc.). With that type of transformer, the amplifier might connect between C and 5W, and the speaker between C and 8 for example but as I said, that's if you're lucky!
- Q:Transformer 1KVA can load how much security, how to calculate the formula
- You only give a parameter, that is, KVA, you have to give two dollars to count
- Q:I have a DC current transformer and it is a 2500:1. I do not know what this means but I have a rectifier hooked up to it and am measuring the output DC voltage. I have hooked up resistors in values of 20Ω, 2kΩ, 10kΩ, and 20kΩ. I do not know how to convert to amperes though the resulting DC volts. How can this be done?
- NO such thing as a DC transformer. Do you mean an AC voltage transformer with rectifiers on the output? But ohms law should apply. Current voltage divided by resistance.
- 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 composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".
