What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Properties of a resistors?
They are used in circuits and devices commonly (eg.the computer and TV) they slow the amount of electrons going through so that if you are plugged into the mains and have a light bulb that is small, the resistor would be put in place to the device eg.the light bulb doesnt burn out.
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.
Can you give an example of an energy transformation from electrical to thermal energy?
A simple electrical radiator. Electrons moving inside the resistor at high speed will collide with the "walls", therefore increasing temperature. Even a standard light bulb works like that. Electrons inide the filament (which is just a thin resistor) collide with the walls, producing both light and heat (actually, more heat than light is produced).
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.

When electrons in a circet pass through a light bulb called the what?
light
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.
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.
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.
