Answer 1

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 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.Series combination of cells

A group of cells connected in a regular order is termed “battery”. Thus the torch light consists of a battery containing two cells connected in a regular order

2. a circuit without interruption, providing a continuous path through which a current can flow.

3. Sometimes an electric bulb does not glow even if it is connected to the cell. ... A break in the filament of an electric bulb means a break in the path of the current between the terminals of the electric cell. Therefore, a fused bulb does not light up as no current passes through its filament.

4. conductor

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.

insulator

An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

No, it can't be covered with aluminum foil as aluminium is a conductor of electricity and we may get electric shock whereas plastic is a bad conductor of electricity so it is used to cover wires.

hope it helps you!!
