Question

Which effect is utilized by an electric bulb ?

Answer 1

Hint: As electricity is passed through the terminals of an electric lamp, it emits light. In the middle of the bulb, there are two thick contact wires with a thin wire connecting them. Filament is the term for this thin wire.

Complete answer:
An electric bulb's thin, high-resistance tungsten filament heats up and emits light as an electric current passes through it. This is the electric current's heating effect.A light bulb is an electrically powered light source. Light bulbs transform energy into light by passing current through a thin wire called the filament. The filament is usually made of tungsten, which emits light as electricity is passed through it.

As an electric current passes through a conductor, heat is produced as a result of the conductor's resistance to the flowing current. Heat is produced in that conductor as a result of the work done to overcome the current's stumbling block.
-Tungsten metal is used to make a dense metallic wire in an electric lamp.
-With a neutral gas or vacuum, the metal is held in an inert state.
-The tungsten wire heats up and emits light as current passes through it.
-The majority of the electric power drawn into the circuit from the electrical source is dissipated as heat, with the remainder released as light energy.

Note: Neon, argon, xenon, sodium, metal halide, and mercury are among the gases used. The basic operating concept is similar to that of a carbon arc lamp, but the word "arc lamp" usually applies to carbon arc lamps, while discharge lamps refer to more common forms of gas discharge lamps.
