Household and industrial devices are designed to convert one form of energy into another to perform useful work. Understanding the type of energy conversion helps in analyzing efficiency, selecting appropriate devices, and designing sustainable systems. One common household device is the electric kettle. An electric kettle converts electrical energy into thermal energy. When plugged in and switched on, the electrical current passes through a resistive heating element, which then heats the water. This process is a direct conversion of electrical energy to heat, making it efficient for boiling water quickly. Another household device is a ceiling fan. A ceiling fan primarily converts electrical energy into mechanical energy. The electrical current powers the motor inside the fan, which rotates the blades, creating airflow and facilitating __________ __________ __________ __________ _________ _______ __________ _________ ______ ______ _________ ____.
