Electricity must always flow into residential and commercial buildings in the modern world in order to run appliances like refrigerators and lights.

Power transformers enable the transmission of electricity to any location when used in conjunction with distribution transformers. Power transformers receive power at very high voltages, which they then step down to lower voltage levels so that distribution transformers can distribute the electricity to individual homes or businesses. The electrical appliances we use can operate at lower voltages or higher current levels.

Large cities' worth of electricity is produced by power generating stations, which also use power transformers. In order to guarantee that the entire city has power, transformers help to increase generated power. Without the usage of power transformers, the power produced by power plants would not be enough to run the entire city. Power transformers are used to meet the varying voltage requirements of modern appliances based on their intended application. Additionally, power transformers shield the electrical gadget from harm or danger by cutting it off from the main power source.
