Transformers are rated in KVA or VA (volt-amps). They transform voltages from one value to another. The current in a transformer is inverse to the voltage. This is why transformers are rated in KVA and smaller ones in VA.

How Convert 9 volt to 230 volt?
Converting 9 volts to 230 volts would require a pretty hardcore step up transformer (Expensive) and you probably wouldn't have enough current to sustain the load.See discussion page for more information.
How do you convert 115 volt into 230 volt?
The only way to do that is with a transformer. They make inline transformers that convert 230 to 115 and they simply plug in inline.
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
What is the electrical current in electrical transformations?
In the case of a transformer the simplest way to explain current is that it will be inversely proportionate to the voltage. For example: If you have a transformer that transforms 5000 volts down to 2500 volts you have a 2:1 ratio. The current ratio will then be 1:2. If you had 200 Amps on the 5000 volt side you will have 400 Amps on the 2500 volt side. Comment There is a misconception that a transformer will 'step up' or 'step down' the primary current. In fact, the secondary current is determined by the secondary voltage and the impedance of the load, NOT by the primary current. The secondary current then determines the primary current by a factor equivalent to the reciprocal of the turns ratio.
How to convert 440 VOLTS to 380 VOLTS?
You can use a transformer to step down the voltage from 440 volts to 380 volts. Make sure to use a transformer that is rated for the required input and output voltage, and have a qualified electrician perform the installation for safety.

What is the formula to convert 240 volt to 12 volts?
If it is AC then you don't need a formula, you just need a transformer.
How do you convert your 110 volt neon sign to run off 240 volt UK socket?
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
How do you convert 240 volts to 1.5 volts?
There are several ways to convert a 240 volt input to a 1.5 volt output. If the 240 volt input is alternating current (AC), a simple transformer can reduce the 240 volts to 1.5 volts (AC). A properly configured resistor or impedance coil in series with the input and output would also do the job but a tansformer also serves to isolate the output from the input offering greater protection for the 1.5 volt device. You If 1.5 volts direct current (DC) is required, a rectifier circuit is needed after the 1.5 volt AC output. If the source is 240 volts (DC), A resistance circuit in series can reduce the output voltage. You can also use electronic circuitry to chop of the 1.5 volts.
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
What device is needed to convert 110 to 220 volt?
For higher current applications you would need a power transformer, for lower current applications you would need an adapter transformer.
What is the kind of transformers that transfers from micro volt to volt?
The type of transformer that can convert from microvolts to volts is a step-up transformer. This transformer increases the voltage level from the input side (microvolts) to the output side (volts) using electromagnetic induction. Step-up transformers are commonly used in power distribution systems to increase voltage for long-distance transmission.
How do you convert 230 volts to 12 volt system?
With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. <<>> It depends on how big of a transformer that you are looking for. There are many control transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.
How much current can a 50 volt ampere 36volt transformer deliver?
I (Amps) = VA / E (Volts) I = 50 / 36 I = 1.39A Do the math!
How do you convert 12 volt to 24 volt?
Use a voltage devider or a transformer.
