A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery

What kind of energy source does a transformer use?
Electrical (alternating current)
How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?
Use a transformer.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is the reason to use open circuit and short circuit methods to find Transformer losses?
The transformer can be tested on open and short circuit to find the iron losses and copper losses separately, which uses a fraction of the power than having to run the transformer on full-load.
What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
What is the use of core transformer?
500w iron core transformer .that kind of size
What kind of transformer do you need to run a ho train with 30 feet of track?
You can't use a transformer. HO models all run on DC current, AC will destroy them. You can buy HO power supplies, and for 30 ft of track almost any one would do.

What capacitor should you use on my step up transformer with an output of 220v so you can use it to run my 220v 60hz motor?
If you have a transformer with an output adequate to run the motor, use it directly for the supply to the motor control circuitry. Remember when dealing with motors, the start current will be about 300% of the full load running amperage. Size the transformer accordingly.
What kind of circuit lowers voltage?
you can use a voltage divider or a step-down transformer to lower voltage.
How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?
Use a transformer.
How many led can connect in series with ac supply?
Usually you'll need 100ohm resistor for each led. In this kind of setting, you will get the LED intensity nonuniform because of its differences due tolerance value. the best thing is to use LED driver IC. Another benefit of using LED driver is, you can mix red led with other color. Now, if we wanted to connect a red LED with a forward voltage of 1.8V and a current of 20mA directly to the transformer output then use the following equation: R=V/I = 9 / 0.02 = 450 Ohms. You could use 470 ohms from the E12 resistor series.
Which type of transformer is use in gss?
Frgi transformer
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer

How do you get 240 volts out of a 110 outlet?
You would have to run new wires to obtain 240 volts or use a step-up transformer.
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
