Which of the following best describes the primary power sources for gas appliances compared to electric appliances?

The primary power sources for gas appliances are accurately described as propane or natural gas, while electric appliances predominantly rely on electricity. This distinction is crucial in understanding how different types of appliances operate.

Gas appliances are designed to function using combustible fuels like propane or natural gas, which are ignited to create heat for cooking or heating purposes. Conversely, electric appliances draw their energy from electrical sources to power heating elements, motors, and other functions.

Understanding this fundamental difference is essential for technicians when diagnosing issues, performing maintenance, or making service recommendations for different types of appliances. Recognizing the specific power sources also helps ensure safety and compliance with local regulations during installation and repair processes.

This knowledge is particularly important as the efficiency and functionality of heating and cooking appliances can vary significantly based on their power source, which can affect energy consumption and overall performance.
