Electrons passing through a lamp gain or lose some voltage as the light the lamp?

No. One of the principles of Physics is that all electrons are identical, and you
can't tell any one electron apart from any other one.
Even their numbers don't change. The number of electrons that come out of the
light bulb is the same number that went in.
What does change on the way through is their energy. They go in with relatively
higher energy, fall through several volts to a level of lower energy, and everything
the electrons lost radiates out of the bulb in the form of electromagnetic energy ...
a lot of heat and a little bit of light.

What happens after an atom stores energy from passing electrons?
The energy is eventually released as light.
Are electrons moving through space called light?
Electrons are very small, and have very small mass, but they are not visible light (photons).
Where do electrons for photosystem II come from?
Water. Photosystem II uses light energy to catalyze the following reaction: 2 H2O --> 4H+ + 4e- + O2 The electrons from water pass through photosystem II to reduce quinone molecules, which shuttle the electrons to the next step of the photosynthetic reaction chain.
What are photovoltaic compounds?
Photovoltaic compounds are compounds that transfer electrons in a circuit when exposed to light. Light (which is a type of electromagnetic radiation) transfers energy into the compound, which causes electrons to be rearranged. This rearrangement can be directed into a wire and results in electrical potential (voltage, electromotive force) that can be harnessed. These compounds form the basis of solar cell technology.
How many electrons are in the filament of a light bulb?
I think you probably know that the flow of electrons causes the filament to heat up and glow when the electricity is switched on and you want to know the number of electrons in the electricity? Well, it doesn't work quite like that, the electrons are all in the electron shells of the tungsten atoms making up the filament and there are the same number of electrons in these shells (and thus he filament) whether the electricity is on or off. When electricity is on, the electrons (in the outer shells) hop from one atom to the next, no extra electrons get into the filament (electrons coming in at one end are balanced by electrons going out at the other end) While all atoms have electrons, not all elements have atoms with 'free' electrons to allow this hopping - these elements will not conduct electricity.
How do you calculate current and voltage passing through light globes?
You can't "calculate" both. If you know the wattage & the line voltage then I = P / E and vice-versa.
What is transmitting light?
Light is said to be transmitting when it is passing through any matter i.e. not through a vacuum but through a gas, liquid or solid. Light waves move at their highest speed when passing through a vacuum and slow down when passing through matter due to their interaction with the electrons around atoms, molecules or crystal lattices. Optical fibres made of special types of glass are used to transmit light signals in a similar way to copper wires used to transmit electrical signals.
What effect has the condenser lens on light rays passing through it?
The condenser adjusts the amount of light passing through the specimen.
The voltage in the home is 110 volts. a light bulb has a resistance of 121 ohms. what is the amperage passing through the bulb?
I=v/r =110/121 =0.909A
Can you split white light by passing through it through a prison?
You can split white light into a spectrum of its component wavelengths by passing it through a prism, not a prison.
Light energy passing through matter unaffected?
Light cannot pass though matter but matter is technically atoms, which are mostly space with a few, moving objects - electrons and the nucleus. For glass, the loss of light through the material occurs for all glass.
What is the passing light through matter?
Transmission
What gives the gray color to the cell body areas?
The amount of light passing through that's reaching your eye or the amount of electrons being absorbed. Depends on the microscope.
What happens after an atom stores energy from passing electrons?
The energy is eventually released as light.
What is light refraction for kids?
the bending of light when passing through an object
Are electrons moving through space light?
No; light is photons.
Do light passing through a prism have a maximum deviation?
no
