What else can I help you with?
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.
Would you expect to find dc or ac in the filament of a light bulb in your home. In the headlight of an automobile?
In the filament of a light bulb in your home, you would typically find AC current since most household electricity is AC. In the headlight of an automobile, you would expect to find DC current, as cars typically use batteries that provide DC power for lighting systems.
Would you expect to find DC or AC in the filament of a light bulb in your home?
The electrical grid in North America uses AC system. Your home is connected to the grid through your utility company. To answer the question, you will find AC in the filament of a light bulb in your home.
Hans christian oersted made the hypothesis that when an electric current flowed through a wire it acted like a?
Magnet. Oersted's hypothesis was proven correct when he observed that a compass needle placed near a wire carrying an electric current would deflect, indicating the presence of a magnetic field around the wire.
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
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 to the current modal of the atom if new information about its is discover in the feature?

What is another word for a filament?
no why would you ask that
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.
Would you expect to find dc or ac in the filament of a light bulb in your home. In the headlight of an automobile?
In the filament of a light bulb in your home, you would typically find AC current since most household electricity is AC. In the headlight of an automobile, you would expect to find DC current, as cars typically use batteries that provide DC power for lighting systems.
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
What would happen if there is no air current?
Number of animals would decrease and it would be almost impossible to breathe.
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 did the first light bulb look like?
The first light bulb was invented by Thomas Edison in 1879. It had a carbonized bamboo filament inside a glass vacuum bulb. When an electric current passed through the filament, it would glow and produce light.
