What device uses a resistor to transform electrical energy into light and heat?
Among others, the filament of an incandescent light bulb is a resistor- which gives off heat and light.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
What is the energy transformation of solar collector?
a solar collector turns light into heat, and uses that heat to create electricity.
Can you give an example of an energy transformation from electrical to thermal energy?
A simple electrical radiator. Electrons moving inside the resistor at high speed will collide with the "walls", therefore increasing temperature. Even a standard light bulb works like that. Electrons inide the filament (which is just a thin resistor) collide with the walls, producing both light and heat (actually, more heat than light is produced).

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.
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?
Stars, light, heat
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.
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.
Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
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
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.
Which gases create the light and heat from sun?
Hydrogen and Helium
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
