In an 'old fashioned' incandescent light bulb, the only electrical part inside is the
filament wire itself. When you put a meter across a cold bulb and measure the
resistance, you're measuring the resistance of the filament. More modern and
more efficient artificial light sources, like fluorescent tubes, LED lights and CFLs,
have additional electronic components inside the structure of the bulb.

What device uses a resistor to transform electrical energy into light and heat?
Among others, the filament of an incandescent light bulb is a resistor- which gives off heat and light.
What is the function of a resistor in a light bulb?
Most light bulbs don't have resistors; they are resistors. The filament introduces resistance as part of its action. The resistance is what makes it glow. Usually, if you use a resistor with a light bulb or other lighting device (neon tube, LED, etc), it is external. Its purpose is to reduce the voltage to match the requirements of the bulb. For instance, with a 50 ohm resistor, you could probably use a flashlight bulb with a 9 volt battery.
What temperature does a filament inside a light bulb reach?
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.

How is resistance used to create light in a tungsten light bulb?
Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.
What device uses a resistor to transform electrical energy into light and heat?
Among others, the filament of an incandescent light bulb is a resistor- which gives off heat and light.
Is a light bulb evacuated?
Yes, the inside of a light bulb is a partial vacuum.
How do you use a light bulb as a resistor when charging a capacitor?
connect the light bulb to the positive wire like a inline fuse and then connect the wire to the battery it should just burn out the bulb
How do you built a very simple circuit?
wire a resistor across a battery. that is about as simple as it gets. the resistor could be an incandescent light bulb.

What gas is inside a light bulb?
The kind of gas that is in a light bulb is called Argon.
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 energies does a light bulb?
A light bulb uses electricity as its source of energy.A light bulb to uses electrical energy which is supplied to a resistor that gives off heat as well as light. The resistor is a thin coiled piece of wire made of Tungsten because it has the highest melting point of any metal.For more information see the answer to the Related question shown below.
