step up or stepdown is done by the ratio of the number of turns in the primary / secondary coil, large number on high voltage side small number on low voltage side. the wire used on the low voltage side would be thicker than the high.

What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
What are transformers designed to operate with?
to step up voltage or to step down voltage
Device used to step voltage up or down?
As transformers do not work with DC., the answer is a voltage divider network (step down) or a voltage multiplier network (step up).
Why you use transformers to transfer power?
Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
What is meant by high and low voltage sides of transformers?
Transformers are use to step up and step down the voltage of electricity. In a step up transformer, the voltage coming out is higher than the voltage going in so the output is the high side and the input the low side. In a step down transformer, the output is the low side.
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
How are step-up and step-down transformers used in the transmission of electric current from the electric company to homes?
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
What are the Importance of transformers?
It is used when u need to step up or step down a particular voltage level.
Where might a step-down transformer be used?
Step-down transformer is used at grid substations for feeding various substations which further step down the voltage for feeding distributing transformers and further step down transformers are used to supply the voltage for the consumer uses
How can you convert 1000000 volts to several hundred 9 volt power sources?
On the whole AC electrical conversions are done with transformers. In your question both step up and step down transformers will be utilized. Step up transformers will be utilized to get the generated voltage up to transmission voltage. At the voltage transmission destination the voltage will use step down transformers to decrease the voltage to the consumers load requirement. Or you could connect 111111 resistors in series and take the voltage off each one of them .. but ull have to put in consideration the load resistance ..
What are the disadvantages of step down transformers?
There are no disadvantages to either step-up, or to step-down, transformers. They do exactly what they are intended to do: change voltage levels while maintaining approximately the same power level on both primary and secondary sides.
