Transformers are used to change the voltage in a circuit from high to low or from low to high. Some of the gadgets that use transformers include surround sound systems, the CPU power supply and speakers which have inbuilt amplifiers.

Why does the national grid use AC current?
transformers
What are some simple electronic devices that are used in electrical engineering?
Resistors, capacitors, inductors, transformers, diodes, transistors, integrated circuits, power sources are the basic building blocks.
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 advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
What are the functions of current transformers and the difference between current transformers and voltage transformers?
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
What are devices that use electromagnets?
Motors Transformers Maglev trains Electric toothbrushes Induction heaters
What are DGA readings of a transformers?
These devices are not transformers, but toroid hall effect sensors. That is how they can sense DC.
Current Transformers Manufacturers?
Macroplast Transformers is a leading Current Transformers Manufacturers in India. Current transformers are devices that transform higher current value to lower current value. Current transformers provide galvanic isolation from the voltage on the primary winding while simultaneously creating a power signal that has been converted to a standard level, which in turn permits the use of standard measurement instruments and relays.

What safety devices are in transformer?
Some small control transformers have a built in primary fuse. Larger transformers are primary fused externally and pole transformers are primary fused externally with the fuse holders mounted on cross arms near the transformer.
What is the largest market for transformers?
The majority of apparatus manufactured in this industry are power and distribution transformers purchased by electric utilities. These devices accounted for about 50 percent of industry shipments in the late 1990s.
Do transformers use kw?
yes
How are the transformers powered?
They use Energon
What coutry using step-up transformers?
All countries use step-up transformers -if that is what you are asking.
How electromagnetism generates rotary movement?
if a component has an electrical connection and movement is created by or within the component, then that component will use an electromagnet. Devices such as relays, solenoids and motors, use electromagnets to create movement. Ignition coils and transformers use electromagnetic induction to raise or lower voltage outputs
What is meant by saturated current?
Different devices have saturation currents. For example transformers and transistors. There is not sufficient information in the question to allow a proper answer.
