What are the effects of the resistance of a filament wire?
The resistance of a filament wire affects the amount of current passing through it and the amount of heat produced. Higher resistance leads to higher heat generation and light emission, resulting in brighter light. However, too much resistance can cause the filament to overheat and fail prematurely.
What happens to the temperature of the filament as the bulb becomes brighter and brighter?
As the bulb becomes brighter, more current flows through the filament, increasing its temperature. This increase in temperature causes the filament to glow more intensely, resulting in a brighter light output.
What did Edison replace the filament with?
Thomas Edison replaced the filament in his incandescent light bulb with a carbonized bamboo filament in 1880. This improvement helped the light bulb last longer and shine brighter.
How does resistance within a light bulb filament produce light?
Resistance within a light bulb filament causes it to heat up due to the flow of electric current. As the filament heats up, it emits light and glows, a phenomenon known as incandescence. The intensity and color of the light produced depend on the temperature of the filament.
How does energy change when it passes through a light bulb filament?
When energy passes through a light bulb filament, it is converted primarily into heat and light. The filament's resistance causes the electrical energy to be transformed into thermal energy, which then emits light due to incandescence. Some energy may also be lost as infrared radiation.

Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
If the electric current in a light bulb slowly increases then why does the filament glow get brighter?
As the electric current in a light bulb increases, more electrical energy is supplied to the filament, causing it to heat up. The filament, typically made of tungsten, has a property called resistance that converts electrical energy into heat and light. As the temperature of the filament rises, it emits more visible light, resulting in a brighter glow. This phenomenon is described by the relationship between temperature and light emission, where increased temperature leads to increased brightness.
When the bulb is the resistance what this tells about the resistance?
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.

What happens to the filament if the bulbs becomes brighter and brighter?
The bulb gets brighter because the filament is getting hotter. If the filament's temperature gets too high it will melt at some point and fall apart. The current will stop flowing and the bulb will "blow".
What makes a light bulb shine brighter?
Increasing the amount of electrical current flowing through the bulb's filament will make it shine brighter. Additionally, using a higher wattage bulb or a bulb with a higher lumen output will also produce a brighter light.
What happens to the temperature of the filament as the bulb becomes brighther?
As the bulb becomes brighter, the temperature of the filament increases. This is due to the increased flow of electricity through the filament, causing it to heat up and emit more light. The relationship between brightness and temperature is direct - the brighter the bulb, the hotter the filament.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
