1. Material that allows electricity to pass through them is called a .

2. Material that does not allow electricity to pass through them is called an .

3. The complete path from one terminal of the electric cell through the bulb and back to another terminal of the electric cell is called an .

4. In an electric bulb, there is a thin tiny wire inside the glass cover called the .

5. All types of electric cells have two terminals, a terminal, and a terminal.

6. While connecting more than one cell in series, the negative terminal is connected with the terminal.

7. The inside portion of the bulb is filled up with gases, like argon.

8. If there is any gap in the path of the circuit, the bulb does not light up. Such a circuit is called an circuit.

9. If a circuit is complete and the bulb lights up, such a circuit is called a circuit.

10. The electric current flows from the terminal of the cell to its terminal.
