Why a bulb get hot when electricity is passed through it?
Step by step answer: In the bulb there is a thin wire, called the filament, which glows when an electric current passes through it. The filament is heated up to a high temperature and becomes white hot. This glowing filament gives light. This is the heating effect of the electric current.
Which effect of current causes the bulb?
THIS IS YOUR ANSWER: Heating effect of current causes the bulb to glow. When the current passes through the bulb then the filament of the bulb gets heated to a high temperature. This causes the bulb to glow.
When electric current is passed through a bulb?
When current is passed through an electric bulb, its filament glows, but the wire leading current to the bulb does not glow because: (A) Less current flows n the leading wire as compared to that in the filament. (B) The leading wire has more resistance than the filament.
When electricity passes through a bulb does it give off light and heat?
Answer: The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
When electricity passes through a bulb it gives off a sound B light C electricity and heat?
Answer: an in incandescent bulb uses heat caused by an electric current. when electrical current passes through a wire it causes the wire to heat. the wire or filaments gets so hot that it glows and gives off light.
Why does current show magnetic effect?
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
What are the three effects of electric current?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
Why a fused bulb does not glow?
One reason for a bulb to fuse is a break in its filament. 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.
How does bulb glow?
The typical incandescent light bulb contains a thin wire (usually tungsten) called a filament that has a high electrical resistance. This filament gets very hot when an electric current passes through it. The intense temperature makes the filament glow brightly.
What happens to the filament when electricity flows through it?
Electricity flows through a thin tungsten wire in the light bulb called the filament. As a result of this resistance, the filament heats up and starts glowing, converting electrical energy to light energy.
