No. Current is a physical flow of electrons. They don't disappear, or magically
appear out of nowhere. When a current of electrons leaves one terminal of a
battery or electric generator, the same number of electrons must eventually
arrive back at the other terminal.
What gets used up is their energy. The ones that leave the generator or battery
are rarin' to go. The ones that arrive back are tired out, and just barely make it
before they collapse, like Roger Bannister at the one-mile mark.

Does the same current pass through each bulb?
no
Construction and working of electric bulb?
initially when current pass through the filament
What is the difference between series and parallel circut?
If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.
Why won't your rear turn signal work?
you probably have a bulb out or, check the wiring to that bulb if the bulb appears to be okay. If it is neither of those the connector may need to be cleaned. Sometimes they get a little oxidation on them and won't allow the current to pass through to the bulb. Good luck.
Can you boil water if you pass electric current through it?
Yes, we can boil water if we pass enough current through it......
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
Is it true the alternating current can pass through a capacitor while the direct current cannot pass through?
Yes.
What voltage is required a pass 0.5 A of current through a 4.5-W bulb?
9 volts====================The question is a bit convoluted.The power dissipated by the bulb and the current through itboth depend on the voltage applied across it.In the real world, the way to ask this question would have to be:If a light bulb dissipates 4.5 W of power when 0.5 A of currentpasses through it, what voltage has been applied across it ?(And, for extra credit, what is the bulb's effective resistance ?)

What is needed to light a light bulb?
Electricity has to pass through the filament which, when it gets hot enough from resistance to the current, begins to glow and give off light.
How do street lights produce light?
They produce light by using mercury vapor :D=======================Answer #2:Some (not many) pass electric current through mercury vapor, causing it to glow violet.Some pass electric current through sodium vapor, causing it to glow yellow.Some pass electric current through a thin wire, causing it to heat and glow ...a process is identical to that in every incandescent light bulb in your house.Some burn natural gas.
When electrons in a circet pass through a light bulb called the what?
light
