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

What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Why in the experiment of flashing and quenching of capacitor the neon bulb start twinkling?
It is due to the charging and discharging of capacitor in the circuit....
How do i charge a schoche 500 capacitor?
Found this online, Credit to: Sonic Electronix Learning CenterStep 1) Remove the fuse for your audio system that connects it to your battery. This fuse is often in-line with the power wire of the amplifier that your capacitor is going to be connected too.Step 2) Wire up your capacitor by following all the instructions in the installation manual. Make sure the power, ground and if applicable the remote turn on wire of the capacitor is connected.Step 3) To begin charging the capacitor you need either a test light or a resistor. Often times these are included with the purchase of a capacitor but can be purchased separately if necessary.A) Using a Test Light: A test light is the simplest way to charge a capacitor. All you need to do is take the power and ground of the test light and stick them in-line where your fuse used to be. You can use alligator clips to simplify this process. Hold the test light in place of the fuse until the light bulb turns off meaning the voltage went from 12V to 0V and the capacitor is charged.B) Using a Resistor: You will need a 1 watt, 30 - 1,000 Ohm (1kohm) resistor for charging your capacitor unless otherwise specified (you capacitor may have a resistor included). Try to use a higher impedance resistor so that the capacitor is charged slowly. This will prevent the capacitor from charging too fast and sustaining damage. Also, a lower wattage resistor will heat up very quickly and could crack or explode so make sure NEVER to hold a resistor with your bare hands. Put the resistor in line with your fuse holder, as though it were the fuse. Place the voltmeter positive node on the positive terminals of the capacitor and the negative node on the ground terminal of the capacitor and set the meter to Volts DC. Once the volt meter reads 11 or 12 volts you can remove the voltmeter and replace the resistor with the power fuse. The fuse may spark when you reinstall it, this is normal and should end quickly.
Why in the experiment of flashing and quenching of capacitor the neon bulb starts twinkling?
because of charging and discharging
What is the resistor in an incandescent light bulb called?
It is the filament.
What has happened when a light bulb has burn out?
it simply means that a wire from the light bulb is joined or connected to the charged plates of the capacitor.resulting to discharged of the capacitor.
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.
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 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.
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.
