Yes, first find out how many volts you need on the output.
For example, I'll go with 240V for a step up transformer.
You would want to put some 10-14 guage wire on the secondary of the transformer, at around 240-250 turns on the transformer. If you can fit thicker wire, then it'll handle more current, but it may blow a fuse once you get such a big transformer.

What is line interphase transformer?
interference line transformer display digit number in electerical device,such as generator it display amps rate&voltage etc.
How do you write a letter to customers informing of rate increase?
As tactfully as possible.
What is mean KVA Rating of transformer?
copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN
The maximum rate of increase of a population is its?
The maximum rate of increase of a population is its biotic potential, which represents the highest possible growth rate under ideal conditions, unaffected by environmental factors such as resource availability or competition.
How you can choose the capacitor range for 24 volt output rectifier?
the high quality way is to rate the capacitor for: 2 times the DC voltage. or 2 times the peak voltage of the transformer. Consumer Industry does not care about prpoduct life span and accepts much less conservative "bare minimum" ratings to reduce cost: 1.5 times the DC voltage. or 10% higher than the peak voltage of the transformer A good 24V supply has a 35V capacitor. Of course the cheaply made product will fail sometime with such narrow margin.
What is the Difference between linear IC and digital IC?
Both linear ICs and nonlinear ICs has an output voltage which is dependent on the input voltage. However, the difference is that linear ICs produce an output voltage which increases or decreases at a "fixed rate" relative to the input voltage. Nonlinear ICs do not do this. A voltage regulator may be considered nonlinear because as you increase the input voltage the output will climb at the same rate (just like linear ICs), however, once the input voltage reaches a particular level point, the output no longer increases as you increase the input. This is at the point where regulation begins. The nonlinear IC no longer changes its output at a fixed rate relative to the input.
What is a device that changes electric current into a different voltage?
Nothing can change electric current to voltage. You can compare "current " to rate of flow, while "voltage" is the energy level. Transformers can be used to increase or decrease the voltages of alternating current as is done from 'street power' to domestic power.
What is the significanse of increasing the number of turns on an electromagnetic coil?
As you increase the number of coils around an electromagnet, the magnetic field around the electromagnet gets stronger. As the electromagnet gets stronger it able to generate or convert more electricity and therefore this increases the efficiency rate of the transformer and hence the transformer is able to convert the voltages passing through it at a higher rate.
Do transformers increase the power output of electric substations ina city?
No. Power is the rate at which energy is flowing through the electrical circuit. If a transformer changed the power, it would have to continuously destroy some of the energy that enters it, or else create more. A transformer changes the voltage and current that enter one side of it into different voltage and current that leave the other side. But it does it in such a way that the product of (voltage x current) is the same on both sides. That product is also equal to the power, so the power that leaves the transformer is the same amount that enters it. (Except for a little bit that becomes heat on the way through, because nothing in the real world is ever 100% efficient.) Now, of course, you should be asking: "Then what's the whole purpose of the transformer, if you only get out of it the same power and energy that you put into it ? Who needs it ?" That's exactly the right question to ask. Post it to WikiAnswers, and I'll answer that one too.
How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
Why transformer ratio is secondary winding voltage by primary winding voltage but not primary winding voltage by secondary winding voltage?
The transformer primary winding is connected to the alternating current supply. This causes a varying current in the primary winding, which creates a varying magnetic field in the transformer core. Because the primary voltage is alternating, the flux is also alternating - expanding and contracting, and changing polarity in time with the supply. This alternating core flux 'cuts' the secondary winding/s of the transformer, and induces a voltage in the secondary coil/s. As long as there is a magnetic field that is moving, and a conductor for it to move across, it will induce a voltage in the conductor. While the actual induced voltage depends on the amount of flux, the amount of conductor material and the rate of change of the flux, the actual voltage can be calculated from: Vsec = ((Vprim * Nsec) / Nprim) where V = voltage, N = number of turns of wire in the coil, prim = primary and sec = secondary. Transformers don't work on DC - they give a brief pulse out at switch-on and switch-off, because that's the only times the current is changing and the flux is moving. If you have to transform DC, you use a switching circuit that 'chops' the DC into a series of pulses that simulate AC as far as the 'moving flux' requirements of the transformer are concerned.
Why rating of transformer is given in kva and that of motor in kw?
A motor's output is measured in watts because it has to supply energy to a mechanical load. The rate at which energy is supplied to a mechancial load is expressed in watts (it wouldn't make sense to express it in electrical units!). A transformer's output is expressed in volt amperes, because this is the product of the transformer's rated output voltage and its rated secondary current -the product of voltage and current in a.c. systems is the volt ampere. In order to express its output in watts, you would need to know the power factor of the load which it supplies (power equals voltage times current times power factor), and the manufacturer has no means of knowing this.
