A transformer is made from two or more coils of wire wound around an iron core. When some voltage is applied to one of the coils it magnetizes the iron core, which induces a voltage in the other coil. There is a turns ratio where of the two sets of windings determines the amount of voltage transformation.
a step up transformer makes a voltage higher than before it does this by having more turns on the secondary coil then the primary coil.
a step down transformer makes a voltage lower then it was before it reaches it, it does this by having less turns on the secondary coil then the primary coil.
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
the transformer voltage can be increased simply by connecting the stepup transformer in series to it. the stepup transformer is nothing but its secondary windings should be more when compared to its primary windings.
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.
the maximum power it will supply
You would use a stepdown transformer.
A stepup transformer increases the voltage to decrease loss of energy due to long distance transmission..
Step up transformer is a transformer (tf) which is used to step up the voltages.for example if we have low voltages in the generating side then we mostly use stepup transformer there.
A step-down transformer produces a secondary voltage that is lower than its primary voltage, while a step-up transformer produces a secondary voltage that is higher than its primary voltage. The primary voltage is the voltage applied to the transformer, whereas the secondary voltage is the voltage supplied by the transformer. It's the transformer's turns ratio that determines whether it is a step down or step up transformer: i.e. the ratio between the primary and secondary windings. If there are less turns on the secondary winding, then it's a step down transformer; if there are more turns on the secondary winding, then it's a step-up transformer.
It is used to step up the voltage in order to transmit it a long distance where it goes into a stepdown transformer and then into your home .
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
a stepdown transformer is used to reduce the voltage and limit the available amperage
Depends on what the voltage is going from - and to.
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
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
Some basic types of transformers are: Step up and Stepdown Transformer, Power Transformer, Distribution Transformer, Uses of Distribution Transformer, Instrument Transformer, Current Transformer, Potential Transformer, Single Phase Transformer, Three Phase Transformer.

A 150kVA transformer, stepdown from 4160V to 600V, 3 phase, will have 20.8A on the primary side and 144.3A on the secondary side assuming the TX is 100% efficient, they are usually 2-3% losses to noise and heat etc.
