What would happen to the filament in an IR lamp if too much current flowed into it?

The answer is no. However, it will run out of electricity if you put a lot of energy into the light bulb when you switch it on. Thank you for asking young fellow person who is unknown to me.

Would you expect to find direct or alternating current in the filament of a light bulb in your home the filament of a light bulb in a car the output of a battery charger?
Light bulb in the home - alternating current (A/C) Light bulb in a car - direct current (D/C) Output of a battery charger - direct current Input of a battery charger - usually alternating current
Why is a copper wire not used to make filaments of electric bulbs?
Because the filament is in effect a resistor. Copper is too good a conductor to provide resistance to the current, and would simply allow the current to complete the circuit. The light is generated by the filament glowing as it heats up in resistance to the current. Tungsten is a much better resistor.
What lasts longer a dimmed light or a fully powered light?
The mechanism that fails in an incandescent lights is the filament. It degrades over time because of current flow. Hence, you would expect the dimmed light (less current) to last longer. This would not necessarily be true for other types of lights.
What happen if a 110 volt lamp connected on a low voltage?
If you had a 60 watt incandescent bulb it would draw about 1/2 amp. That means that the resistance of the bulb filament would be about 220 ohms. Now if you applied 12 volts DC across 220 ohms you would draw about .05 amps. This would not be enough to heat the filament and create any useful light. Remember Ohm's Law says Volts = Amps x Ohms.
Is non ohmic filament better than ohmic filament?
How can a filament give off heat without resistance?Another AnswerThe terms, 'ohmic' and 'non-ohmic' refer to whether or not a material obeys Ohm's Law. It has NOTHING to do with whether a filament is resistive or not!Ohmic materials obey Ohm's Law; non-ohmic materials do not.GSL incandescent lamps generally use a filament made of tungsten. If you were to apply a gradually-increasing voltage to that filament, and note the corresponding values of current and, then, plot the results in the form of a graph, you would find that the graph is a curve. For Ohm's Law to apply, the current must be proportional to voltage for variations in voltage and this is ONLY true for a straight-line graph. Tungsten, therefore, is non-ohmic and does not obey Ohm's Law.Tungsten is chosen for lamp filaments because it can withstand very high temperatures without failing. This is the main reason that it is chosen, NOT because it is non-ohmic.

Do light bulbs use more energy over time?
An incandescent light bulb is essentially a wire through which current flows. The wire gets heated up and glows giving off light. According to Ohm's Law Volts = Current x Resistance. In this case resistance is the resistance of the filament. Since in a residence the voltage remains more or less constant, the way more energy would be use is if more current passed through the filament. If the resistance of the filament decreased then the current would increase. Not sure how an aging bulb would have a decreased resistance. If this were somehow possible such that the composition of the filament changes and reduced resistance then the energy required to operate the bulb would increase.

What would happen if there was no California current?
Its climate would be warmer. :)
Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!

What would happen inside a light bulb if it was filled with air?
It would no longer work. Light bulbs are usually under vacuum and if air gets in the filament blows.
What would happen if you reduced the resistance in a circut?
current will increase
What would happen if electromagnetic induction was not discovered?
there's no current
Why is argon used in lamp?
The traditional bulb contains a thin wire(AKA filament) that gives off light(and heat) when it's heated white hot by a current passing through it. If you were to do this in ordinary atmosphere the filament would simply burn off. But if you put the filament either in vacuum or in a non-reactive atmosphere it can glow w/o burning.
Why do you use Argon in a light bulb instead of oxygen?
The current flowing through the filament causes it to heat to a very high temperature - so high that is becomes incandescent (glows) and gives light. If the bulb was filled with oxygen then, at those high temperatures, the filament would oxidise - burn out - and the bulb would be "blown".
What would happen if there is no air current?
Number of animals would decrease and it would be almost impossible to breathe.
