What is the physics behind fan?
Can a fan run without capacitor? Yes. You can run the ceiling fan without a capacitor by manually spinning the blades. When you give manual spin to the blades, the ceiling fan starts to spin in that direction. Since this manual process is cumbersome hence a capacitor is attached to the ceiling fan to make it self-starting. Is fan rolling friction?
