Question

How does the circuit get completed in a torch?

Answer 1

A torch bulb is made up of spherical glass which is attached to a metallic base. There is a filament inside the bulb. The filament is attached to two wires. One of the wires is attached to the metallic base of the bulb. Another wire is attached to the side of the metallic portion of the bulb. The side of the bulb is the negative pole, while the bottom is the positive pole.
Connecting the torch bulb to the cell:For this, you need to attach the wires to the two ends of the cell. The positive pole of the cell should be connected to the positive terminal of the bulb. Similarly, the negative pole of the cell should be connected to the negative terminal of the bulb.

Answer 2

connecting these two ends allows an electric current to flow between them wires provide a path through which current can flow from one end of a battery to the other insulators keep the conductor inside a wires from touching each other and interrupting the flow of electrons
