The filament of a light bulb isn't like a resistor ... it is a resistor. The only difference from the ones on circuit boards is the it's designed to operate at a much higher temperature. So hot that it glows. The glass envelope is there to prevent oxygen from getting in and promptly burning it. When the filament becomes too hot it breaks breaking the current that was lighting it in the first place. That is why the light bulb "burns" out.

Can a pickle light up a light bulb?
Yes, a pickle can light up a light bulb if it is used to complete an electrical circuit. Pickles contain electrolytes that can act as conductors of electricity, allowing them to power a simple circuit and light up a small light bulb.
How many watt does a 60 watt light bulb use if turn it on and off?
If you turn a 60 watt light bulb on and off, it will still consume 60 watts when it is turned on. The act of turning it off does not reduce its power consumption when it is on. However, when the light bulb is turned off, it consumes no power.
Does the length of the wire affect the brightness of the bulb?
Wire has a certain amount of resistance. As electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp. So, the longer the wire, the less voltage the lamp gets, and the dimmer it will be.
Is it possible to light a bulb with raw peanuts?
Yes and no. If the peanuts are moist, not dried, they will act an electrolyte between two dissimilar metal electrodes - zinc and copper for instance - and form a cell that would power a low-volt lamp. The peanuts would be best if ground into a paste to ensure good contact and a continuous path between electrodes. The is also possible with something like a whole apple or potato as well, just push the electrodes in, but what is really powering the lamp are the chemical reactions at the electrodes.
Which of these can act like a prism causing the visible light spectrum to be seen in a rainbow across the sky?
Raindrops in the atmosphere act as prisms, dispersing sunlight and creating rainbows when the light is refracted and reflected within them. This phenomenon results in the separation of different wavelengths of light, creating the familiar rainbow colors in the sky.
Is a light bulb a conductor?
No, a light bulb is not a conductor. A light bulb is made of materials that act as insulators, such as glass and tungsten. The filament inside the light bulb serves as a resistor to generate light when electricity passes through it.
Do a light bulb acts as a resistor in the flow of electrons?
No, a light bulb does not act as a resistor in the flow of electrons. A light bulb converts electrical energy into light and heat through the resistance of its filament. Resistors are passive components specifically designed to control the flow of electric current in a circuit.
Is it true a light bulb acts as resistor in the flow of electrons?
While a light bulb does not technically act as a resistor, in practice it does impede the flow of electrons due to its resistance. As electrons pass through the filament of the light bulb, they encounter resistance, which causes them to release energy in the form of heat and light. This phenomenon is what allows the light bulb to produce light.
Is it correct to say that a bulb in a circuit is a resistor?
Yes it is. The filament in a standard incandescent bulb is a type of resistor. An incandescent light bulb contains tungsten which reduces electricity and converts electricity to heat and light. All incandescent bulbs are resistors, but only a fraction of resistors are bulbs. If you want to see if a bulb is a resistor, try adding another bulb in series without changing the voltage. Both bulbs will be very dim. Another way to test this is to get a multimeter and set the meter to the resistance setting. If you get any value other than zero, then it is functioning as a resistor.
What is the function of a filament?
On a standard incandescent light bulb, the glass traps a set of gases around the filament that help keep the filament from burning up quickly. (The filament is the part that does the actual glowing inside the glass.) It also keeps the oxygen in the air that we breathe away from the filament. Oxygen is one of the gases that will vastly accelerate the destruction of the filament. (Also, the glass keeps anything from touching the electrical conductors inside.) The glass can also act as a filter to remove any ultraviolet radiation caused by certain types of light bulb's ("lamp's" technically) methods of creating a arc to produce light. When specially teated, the glass can also be used to break up the light rays to cause more diffused source of light. (Think "Soft White" to get an idea.)

(Think "Soft White" to get an idea.)
What type of energy transformation occurs when a light bulb is turned on?
Electricity is transformed into light and heat energy when a light bulb is turned on. The electrical energy is used to heat up the filament in the bulb, causing it to glow and emit light. Some of the electrical energy is also converted to heat energy due to resistance in the filament.
What would a light bulb act as in a circuit?
A light bulb would act as a load in a circuit. It transforms electrical energy into light energy and heat when current passes through it. It offers resistance to the flow of current, causing it to light up.
Can a pickle light up a light bulb?
Yes, a pickle can light up a light bulb if it is used to complete an electrical circuit. Pickles contain electrolytes that can act as conductors of electricity, allowing them to power a simple circuit and light up a small light bulb.
What is the hypothesis of a light bulb using a lemon?
The hypothesis regarding using a lemon to power a light bulb would be that the acidic juice of the lemon can act as an electrolyte to facilitate a chemical reaction with the metal electrodes of the light bulb, generating enough electricity to produce light.
What was George Washington's role in the judiciary act of 1789?
He invented the light bulb
Why does a light bulb get lit up by a lemon?
A lemon can act as a battery due to its citric acid content reacting with the metal electrodes in the light bulb. The electrolytes in the lemon facilitate a flow of electrons, creating a small electric current that can light up the bulb.
