electrical energy is converted to heat energy as a result of the resistance of the filament. This filament then incandesces as a result of the heat. In the absence of oxygen the filament will not burn.
In gas lights (flourescent, neon etc.) the gas trapped in the bulb is electrically ionized at high voltage causing the gas to flouresce with less heat, due to lower resistance across the cross section of the bulb as opposed to the cross section of a filament.
**the voltage necessary to produce the flourescing of the gas is dependent on the distance between the electrodes in the bulb. It needs to be high enough to "jump" the gap initially between the electrodes, the ionized gas then becomes conductive itself and "closes" the circuit, reducing the energy consumed.
*** Gas lights require a larger initial electrical charge to begin ionizing the gas, thus by turning them on and off frequently requires a higher energy use than leaving them on.

What energy transfer takes place when the current passes through a resistor?
When current passes through a resistor, electrical energy is converted into heat energy, which causes the resistor to heat up. This process is known as Joule heating.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
Why does the current loose some of the energy when it passes through a bulb?
When current passes through a bulb, it encounters resistance in the filament of the bulb. This resistance causes some of the electrical energy to be converted into heat and light, resulting in a loss of energy in the form of heat radiation.
What do waves transfer from one place to another?
Waves transfer energy from one place to another. This energy can travel through mediums such as air, water, or solids, causing the particles in the medium to oscillate as the wave passes through.
What is the energy transfer of an electrical to a light?
The energy transfer from electrical to light energy occurs when an electric current passes through a light bulb. The electrical energy is converted into light energy and heat as the filament inside the bulb emits photons, producing visible light. This process is known as electrical illumination.

When current passes through a resistor, electrical energy is converted into heat energy, which causes the resistor to heat up. This process is known as Joule heating.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
When a current passes through a resistance what is the electric energy that is lost?
Becomes heat.

Does the resistor store some energy?
No, resistors do not store energy. They dissipate electrical energy in the form of heat when current passes through them.
Why Does a bulb glow when an electrical current passes through it?
When an electrical current passes through a bulb, the electrons in the filament (usually made of tungsten) gain energy and move to higher energy levels. They then release this energy in the form of light and heat, causing the bulb to glow. This process is called incandescence.
How do resistors work in a circuit to regulate the flow of electric current?
Resistors work in a circuit by impeding the flow of electric current, which helps regulate the amount of current that passes through the circuit. They do this by converting electrical energy into heat energy as the current passes through them, which reduces the overall flow of current in the circuit. This helps control the voltage and current levels in the circuit, allowing for proper functioning of electronic devices.
How does energy transfer in a lamp work?
In a lamp, electrical energy from the power source is converted into light and heat energy. This transformation occurs when the electric current passes through the filament inside the bulb, causing it to glow and emit light. Some of the electrical energy is also converted into heat energy, which can be felt as warmth when the lamp is on.
How does the medium transfer the energy of a mechanical wave?
In a mechanical wave, energy is transferred through the vibration of particles within the medium. As the wave passes through the medium, each particle moves back and forth, transferring kinetic energy to neighboring particles. This transfer of energy continues throughout the medium as the wave propagates.
