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 is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
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 an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
What provides energy to 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.

What are 3 function examples of resistor?
A resistor is really anything that uses electricity along an electric circuit, for example a light bulb, a computer, a radio, etc.
What is the resistor in an incandescent light bulb called?
It is the filament.
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.

What is the function of the Bulbing?
the function of an bulb is it to light up
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.
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.
