If current passes through the bulb not using it up then how battery becomes weak after sometime?

    $\begingroup$ Welcome to PhysicsSE! The title of your question does not match the body of your question. Could you please fix this, as well as give more detail in your question body? I am currently (pun always intended) confused as to what you really want to know here. $\endgroup$ – Aaron Stevens Jan 15 at 14:15
  • $\begingroup$ Are you asking about the workings of a battery or about the general concepts of currents and voltages in electronics? $\endgroup$ – Steeven Jan 15 at 14:20

    $\begingroup$ I'm voting to close this question as off-topic because the answer is found in multiple elementary textbooks. $\endgroup$ – ZeroTheHero Jan 15 at 14:35

  • $\begingroup$ Please re-open. It is obvious to me what they are asking (essentially, why do batteries stop working if they don't lose or gain electrons) and it is not a duplicate of the link provided, which is similar but different. $\endgroup$ – Maury Markowitz Jan 15 at 20:21

The bulb needs a lot of current to produce light, a little current does not make light but still uses the battery.
