2. One is referred to as a positive terminal, while the other is referred to as a negative terminal.
3. The electric bulb's filament is connected to its terminals.
4. These two terminals are fixed in place so that they do not touch each other.
5. When an electric current passes through an incandescent bulb, it glows.
6. In a closed electric circuit, the electric current flows from one terminal of the electric bulb to the other.

Thus, In the given figure, label $3$ and label $4$ are the terminals of the bulb.
