Why does the filament of a bulb glow when current flows through it?
Because the atoms of the filament convert the energy into light energy through a reaction of the electrons, though it does also emit thermal energy. When the current passes through the filament, it excites the atoms and most specifically the electrons (the higher the energy content, the further away they orbit the nucleus of the atom) and makes them vibrate, which in turn causes the electrons to move further afield as they absorb the energy. This causes the radiation of light. This is why filaments do not need electricity to work, merely a significant transference of energy.
What passes through a medium?
energy is independent of medium it passes through?
Can electricity still pass through a bulb which has fused?
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
Why is there a change in rate of energy exchange as time passes?
There is a change in rate of energy transfer as time passes because of the amount of energy in both objects. -probably wrong
What happens to the electrical energy when it passes through a light bulb?
In a traditional light bulb, the electrical energy is converted to heat. The filament gets hot and emits the thermal energy as light. The electrical energy itself is not directly converted to light but goes through the thermal energy stage.There are many kinds of lights and more complicated processes which are not described in this brief answer.

The energy won't change
What happens to the electrical energy carried by the current when it passes through the filament of a bulb?
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.
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.
Does a flashlight form electricity?
No it does not FORM it. It converts chemical energy in the battery cell into electrical energy which is then passed through a thin wire called the filament at the bulb. The filament lights up when electricity passes through it, thus giving out light.

Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
What passes through a medium?
energy is independent of medium it passes through?
What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
What makes a bulb light?
In simple terms, the current passes through the tungsten filament present in the bulb which causes it to heat instantaneously into red hot to white hot and hence light energy emits.

If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
