Astudent makes the following statement
i think that the current is used up when it go through the bulb.
this is what allows the bulb to light
how would you respond to this student useidence and your model to support your ideas

The current is not used up. The electrons flow through the entire circuit and this travel is the current. They flow until they are not charged anymore. That is also why the circuit must be closed or else electrons would escape not just light it up for a second then go out.

Explanation:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
