What device uses a resistor to transform electrical energy into light and heat?
A device that uses a resistor to transform electrical energy into light and heat is an incandescent light bulb. The resistor, also known as a filament, has high resistance, which causes it to heat up and emit light as a result of the electrical current passing through it.
Do a light bulb acts as a resistor in the flow of electrons?
No, a light bulb does not act as a resistor in the flow of electrons. A light bulb converts electrical energy into light and heat through the resistance of its filament. Resistors are passive components specifically designed to control the flow of electric current in a circuit.
Is it true a light bulb acts as resistor in the flow of electrons?
While a light bulb does not technically act as a resistor, in practice it does impede the flow of electrons due to its resistance. As electrons pass through the filament of the light bulb, they encounter resistance, which causes them to release energy in the form of heat and light. This phenomenon is what allows the light bulb to produce light.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Does light contains heat?
Light itself does not contain heat. Heat is a form of energy that is associated with the motion of particles in a material. Light, on the other hand, is a form of electromagnetic radiation that does not have mass and does not create heat on its own. However, when light is absorbed by an object, it can be converted into heat energy.

What if you were to add a resistor to a series circuit that include a light bulb?
A resistor slows the flow of electricity, and converts the electrical energy into heat. You don't WANT heat - you want LIGHT, so we generally do not put resistors in lighting circuits. If there is a resistor in the circuit, it will cause some of the energy that would normally be converted to light to be converted into heat instead, so the light bulb will glow less brightly. A variable resistor in such a circuit is sometimes called a "dimmer".
What is the noun in this sentence Stars create light and heat?
Oh, dude, the noun in that sentence is "Stars." It's like the main character of the sentence, the one doing all the work to create light and heat. Without it, the whole sentence would just be like, "Create light and heat," which is pretty boring if you ask me.
Why is a resistor heated by a ac current?
A resistor is heated by any power source, AC or DC. Voltage is joules per coulomb. Current is coulombs per second. Voltage times current is work in watts or joules per second. This is heat transfer, and is manifest by the resistor getting warm. Actually, any device that dissipates power will get warm. Some of the heat energy is consumed in doing other work, such as in producing light in a light bulb, but much of it also produces heat, also such as in producing heat in a light bulb.
How is resistance used to create light in a tungsten light bulb?
Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.
How is heat made by electricity?
There are many ways how electricity can create heat. For example, passing a current through a wire of high resistance (i.e. a resistor) will generate heat, though not much.
How do you set the sensitivity of a light dependent resistor?
using a variable resistor we can adjust the sensitivity of a light dependent resistor
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What is Light dependence resistor?
A LDR or light dependant resistor is a resistor that works when light is not shining on it, so if there is light on it it will not resist a current, you can also get them to work the other way.
Do a light bulb acts as a resistor in the flow of electrons?
No, a light bulb does not act as a resistor in the flow of electrons. A light bulb converts electrical energy into light and heat through the resistance of its filament. Resistors are passive components specifically designed to control the flow of electric current in a circuit.
How do you find power generated in a resistor?
The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
Which gases create the light and heat from sun?
Hydrogen and Helium
