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.
What else can I help you with?
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.
List a following devices that use electromagnetism to work?
Some devices that use electromagnetism to work include electric motors, generators, transformers, solenoids, and magnetic resonance imaging (MRI) machines.
What are DGA readings of a transformers?
These devices are not transformers, but toroid hall effect sensors. That is how they can sense DC.
What devices instrument that use electromagnets to operate?
Some devices that use electromagnets to operate include MRI machines, transformers, electric motors, and loudspeakers. Electromagnets are used in these devices to generate magnetic fields that can be controlled and manipulated to perform specific functions.
What are devices that use electromagnets?
Some devices that use electromagnets include electric motors, speakers, relays, and MRI machines. Electromagnets are used in these devices to convert electrical energy into mechanical motion or to produce a magnetic field for various applications.
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.
How are the transformers powered?
They use Energon
Do transformers use kw?
yes
What is the significance of the relative permeability of iron in the context of electromagnetic devices?
The relative permeability of iron is important in electromagnetic devices because it determines how easily magnetic fields can pass through the material. Iron has a high relative permeability, which means it can enhance and concentrate magnetic fields, making it ideal for use in devices like transformers and electromagnets. This property allows for efficient energy transfer and control in these devices.
What coutry using step-up transformers?
All countries use step-up transformers -if that is what you are asking.
What devices are based on the magnetic effect of current?
Devices such as electric motors, transformers, inductors, and magnetic-based sensors utilize the magnetic effect of current. These devices rely on the interaction between electric current and magnetic fields to operate effectively in various applications.
