As long as the transformer is capable of 12 Volts DC output, you can use any transformer with HO scale equipment.
you use the pencil
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.
If these are the exact voltages that you need you will need an auto transformer to obtain these voltages. If these voltages are nominal voltages and are of a three phase four wire configuration, the 220 voltage can be obtained from the three phase legs to the neutral (ground) connection. The equation to use is 400/1.73 = 231 volts.
use your hands
Frgi transformer
yes we can place auto transformer in place of original transformer
Yes you can, but I prefer mine to be to scale.
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
why should we use pulse transformer rather than ordinary transformer
we cannot use transformer because transformer cannot change frequency . . .
A transformer is not 'necessary'. The human race evolved, and developed cultures, societies, disease resistance, and technology, without ever seeing a transformer. But there are specific situations in which desirable things can be accomplished much more effectively and efficiently with a transformer than with any other device or method. Here are a couple of examples: -- If the voltage you have available is not the voltage you need, then you can use a transformer to make the change. (But that only works for AC.) -- You can use a transformer to change the output impedance of an amplifier to the impedance of the speaker or earbuds you want to use with it.
Yes, If you have the right objects. All you need is a thomas train set. Make great train rides and use people as visitors. Great!
