The electrical symbol for a bulb is a circle with a cross inside it. The cross represents the filament inside the bulb.
The electrical foot contact in a light bulb serves as a connection point for the electrical current to flow into the bulb. It ensures that the electrical circuit is completed when the bulb is screwed into a socket, allowing the filament or LED components to illuminate. This contact is essential for the bulb's operation, enabling it to produce light when powered.
A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).
