Will a diode work as a light dimmer when switched or added in series to an incandescent 120 volt AC bulb?

Actually, I have seen this in a respected electronics magazine (Elektor) quite some time ago: A diode (selected to be capable to handle the amps, the voltage and the heat from the bulb - if placed inside the lighting fixture) is used to "cut off" one half of the AC sine wave and thus sending pulses of 120V to an incandescent light bulb, simulating a simple dimming device. The proposal was meant to run 240V bulbs at 50% of their brightness but I am pretty certain this concept can be used to run 120V bulbs from 240V power.
One other way of connecting 120V bulbs to 240V would be to connect two 120V bulbs OF THE SAME WATTAGE in SERIES, so the two bulbs form their own voltage divider. Not sure what happens if one bulb burns out - I would expect the other one to blow too, as a dying light bulb represents zero Ohms (plasma/arcing) for a few milliseconds before it goes dark forever.Wiki User

Why do bulbs get dimmer in series circuits?
When light bulbs are connected in series circuits, they will get dimmer whenever a bulb is added. This is because the current is shared between all of the bulbs equally.AnswerLamps only operate at their rated power when subjected to their rated voltage. If you connect lamps in series, each lamp will be subject to a lower voltage, so they will not operate at their rated power and, so, will be dimmer. The more powerful lamps will actually glow less than the less-powerful lamps because their resistance is lower and the voltage drop across them will also be lower than the voltage drop across the less powerful lamps.
What would happen to a series circuit if another bulb was added?
A: Adding any resistance bulbs or whatever in a series circuit will reduce current and will reduce total power. In this case the bulb will glow dimmer as any additional bulbs are placed in the series circuit. this is true if the same input source is kept constant.
What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
If a new bulb is added and the electrical circuit becomes dimmer is it a parallel circuit?
No it's series circuit.
In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?
By adding more light bulbs
What are the uses of series connection?
Disadvantage of series connection: 1.If one point breaks in the series circuit, the total circuit will break. 2.suppose if you want to connect 3 bulbs rated 230v,5A in series then due to added up resistance less current flows and the bubs are dimmer

In a parallel circuit with three bulbs?
All of the bulbs will become dimmer as more bulbs are added.
Why does incandescent light not glow on material?
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
What would happen if another bulb was added to another series circuit?
In a series circuit, if another bulb is added, it is going to dim.
When additional stops are added to a control circuit should they be connected in series or parallel?
series

The ICC raids and instances were added over a series of patches.
