Every electrical device has its operating range of voltage and current for which it is designed for. If it exceed the operating range of voltage, its insulation will damage and device will not work. 220V bulb means the normal working voltage for this bulb is 220V. It can operate on the voltages with a deviation of 5% voltage variation also. this variation depends on the devices and will vary with the manufacturer.
Power is current times voltage, so a current of 0.5 amperes and a voltage of 220v across a bulb will yield a power of 110 watts.
This bulb is very likely to be burn out since the 440 supply voltage is very higher than it's rated voltage.

You can make this conversion if a full wave bridge rectifier is used. Make sure that the diodes are rated for the voltage that is being used.
The reading "100W-220V" on an electric bulb indicates that it is a 100-watt bulb designed to be used with a voltage of 220 volts. This information helps ensure that the bulb is used with the correct power supply to operate efficiently and safely.
The light bulb should still have the same limit - 100 watts, because the limit is set practically by how much heat they produce. You need to make sure the wiring in the chandelier is correctly insulated for the higher voltage.
Power is current times voltage, so a current of 0.5 amperes and a voltage of 220v across a bulb will yield a power of 110 watts.

The equation that you are looking for is I = E/R. Amps = Voltage/Resistance in ohms.
When the electric bulb is operated at 110V instead of its rated 220V, the power consumed will be reduced to 25W. This is because power is proportional to the square of the voltage, so halving the voltage will quarter the power consumed (P = V^2/R, where R is constant for the bulb).
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.
If you can use it in your lamp it will be a 20 watt bulb
It may work if the base is the same but it would only be half as bright.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one. The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.
A 60 watt incandescent bulb using 120 Volts draws about one-half amp. Watts = Volts x Amps (For a resistive load). By Ohm's Law Volts = Current x Resistance so R = 120 V / .5 A = 240 Ohms. Doing the same math for a 40 watt bulb you get 360 Ohms.
