An electric fan is a device that uses electricity to create airflow. It typically consists of rotating blades that push air, providing a cooling effect in indoor spaces. Fans come in various types, including ceiling fans, table fans, and floor fans, each designed for different uses and settings. Electric fans are commonly used in homes, offices, and public places to improve comfort during hot weather. They can help reduce the temperature in a room and increase air circulation, making it easier to breathe. Unlike air conditioners, electric fans do not lower the air temperature but create a wind-chill effect that feels cooler.
