What happens to the metal filament of a lightbulb as you pass electricity through it?

What happens to the metal filament of a lightbulb as you pass electricity through it?

In an incandescent type of bulb, an electric current is passed through a thin metal filament, heating the filament until it glows and produces light. After the electricity has made its way through the tungsten filament, it goes down another wire and out of the bulb via the metal portion at the side of the socket.

When electric current flows through a filament?

here is your answer: When electric current flows through a filament of electric bulb , the filament gives out heat..

How does the current through a filament lamp affect its resistance?

A filament lamp is a common type of light bulb. This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases. The current flowing through a filament lamp is not directly proportional to the voltage across it.

What happens to the bulb when current is passed?

When electric current is passed to an electric bulb, resistance of the spring like structure joined between two points in the Bulb. This causes it to heat and hence it produces Light. It involves conversion of electrical energy to Light energy.

What is used in filament of bulb?

tungsten
The filament used in the bulb is tungsten. It is a rare metal extracted from the ores of wolframite and scheelite. It is a lustrous and silvery white metal. Tungsten has the highest melting point.

What is the resistance of a filament lamp?

As the filament within an incandescent lamp heats up, there is a significant change in the resistance between the off state and when it is operating. A typical 60W bulb operating at 250 volts will consume 0.24 amps and have a resistance of 1041Ω or thereabouts.

How does the resistance of a filament lamp change as PD increases?

As the potential difference across the filament lamp increases the current across the lamp also increases due to Ohm’s law. The increase in current flow also causes the lamp to heat up which causes the resistance of the lamp to also increase.

What happens when electric current is passed to an electric bulb?

What happens when an electric current is passed through an electric bulb Class 6?

Answer: Function of an electric bulb is to produce light energy from the electricity passing through its filament. The filament gets heated up as the electricity passes through it.

When electric current flows through a wire it gets heated which is termed as the effect of electric current?

Explanation: When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called the heating effect of current.

What is light effect of electric current?

When electric current flows through the conductor of high resistance, first it becomes very hot and then glows to emit light. This is called the lighting effect of electric current.
