Question

When a fan turns electricity into motion, what happens to the energy that is not used to spin the blades?

Accepted Answer

When a fan runs, it doesn&#x27;t turn all the electricity into motion. The leftover energy turns into heat. This happens because of friction, which is the resistance that occurs when parts rub against each other inside the motor. Think of it like rubbing your hands together really fast; your hands get warm because the motion creates heat. Some energy also escapes as sound, which is just vibration in the air. The internal wires also create a bit of heat because they have natural resistance, meaning they don&#x27;t let electricity flow through them perfectly smoothly. Even though the fan feels cool to us, the motor itself is actually warming up as it works because of these energy losses.
