AC (alternating current) supply is used in our homes primarily because it is more practical and efficient for transmitting electricity over long distances from power plants to residential areas. AC can be easily transformed to higher voltages for efficient transmission over power lines and then stepped down to safer voltages suitable for household use. This capability reduces energy losses during transmission and distribution, making AC the preferred choice for supplying electricity to homes.
AC is used in our homes because it is capable of easily being converted to different voltages using transformers, which allows for efficient distribution and utilization of electricity. This flexibility in voltage transformation ensures that electricity can be safely and effectively delivered to various types of appliances and devices in residential settings without the need for complex and costly conversion mechanisms.
AC is chosen for electricity supply because it can be easily generated using AC generators (alternators). AC generators are efficient at converting mechanical energy into electrical energy through the principle of electromagnetic induction. They can operate at different speeds and frequencies to match the requirements of various electrical systems, making them versatile for producing electricity for residential consumption.
AC generators are used in homes because they can produce alternating current directly, which aligns with the grid systems used for electricity distribution. By generating AC, generators can synchronize with the grid and contribute to the overall supply of electricity to residential areas. This synchronization ensures stability and reliability in the supply of electrical power to homes.
AC supply is preferred for consumers in homes because most electrical appliances and devices are designed to operate on AC. AC can be easily transformed to different voltages and frequencies suitable for various types of equipment, ranging from lighting and heating systems to electronics and appliances. This compatibility with consumer devices ensures that AC supply meets the diverse energy needs of households efficiently and effectively.
