To calculate the temperature of a light bulb, you can use the Stefan-Boltzmann law, which relates the temperature of an object to the amount of radiation it emits. You would need to measure the power output of the light bulb and its surface area to calculate the temperature. Keep in mind that the temperature of a light bulb can vary depending on factors like the type of bulb and how it is being used.
What else can I help you with?
What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.
How do you calculate the efficiency of a light bulb?
To calculate the efficiency of a light bulb, you would divide the light output (measured in lumens) by the power input (measured in watts). This will give you the number of lumens per watt, which is a measure of how efficiently the light bulb converts electricity into visible light. The higher the lumens per watt value, the more efficient the light bulb.
What forms of energy are given off by a light bulb?
A light bulb gives off mainly light energy as well as heat energy. When electricity flows through the filament in the bulb, it gets hot and emits light.
How do you work out the current of a light bulb?
You can use Ohm's Law to calculate the current of a light bulb by dividing the voltage across the light bulb by its resistance, which is typically provided on the bulb itself or its packaging. The formula is: Current (I) = Voltage (V) / Resistance (R).
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
A very hot light bulb produces more blue light than a light that is cool to the touch. As the temperature of the bulb increases, it emits higher energy photons, which are in the blue-violet part of the light spectrum. Cooler bulbs emit more red and infrared light.
Can you get a wart from a hot light bulb?
You can't get a wart from a hot light bulb.
Is a light bulb is a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.

How hot is a 15 watt light bulb?
120
What forms of energy are given off by a light bulb?
A light bulb gives off mainly light energy as well as heat energy. When electricity flows through the filament in the bulb, it gets hot and emits light.
Why does a light bulb turn black?
A light bulb turns black when the filament inside it gets too hot and starts to burn, creating a layer of soot on the inside of the bulb.
How do you work out the current of a light bulb?
You can use Ohm's Law to calculate the current of a light bulb by dividing the voltage across the light bulb by its resistance, which is typically provided on the bulb itself or its packaging. The formula is: Current (I) = Voltage (V) / Resistance (R).
Why are light bulbs so hot when they are turned off?
light bulbs are hot because the coils spread heat around the bulb.
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
A very hot light bulb produces more blue light than a light that is cool to the touch. As the temperature of the bulb increases, it emits higher energy photons, which are in the blue-violet part of the light spectrum. Cooler bulbs emit more red and infrared light.
What makes a bulb light?
In simple terms, the current passes through the tungsten filament present in the bulb which causes it to heat instantaneously into red hot to white hot and hence light energy emits.
