Using wires and a battery, we''ve insisted that the voltage across the resistor be exactly 5V, and the resistor has no choice in the matter, but it does have a say in how much current flows. It will pass exactly the right amount of current to satisfy the condition that the voltage across it be equal to the product of the current through it and

Your actual question seems to be "Why does the LED turn off if the high current is going through the short?". And the answer is that a voltage source (like a battery) can only supply so much current. Some Googling seems to suggest that a typical battery can only deliver around $1, mathrm{A}$ of current or thereabouts; I don''t know if this is
Guide why does higher current mean lower discharge capacity
Watts are volts*amps or in your cases battery voltage times 1A, or battery voltage * 2A. So twice the power for half the time is the same amount of energy drained from your battery. EDIT: If the question is why would the battery capacity decrease over the expected ideal, then Brian''s comment is the answer.

If you add more resistors in series the effect will be the opposite of what you say: the battery will last longer. A battery has a certain rated capacity, written in mAh (milliamps times hours).

Alright, this can actually be pretty easily explained without too many equations and only a single thing to keep in mind: charge cannot pile up inside a metal. In other words, electrons won''t ever pile up within a wire.

6 Frequently Asked Questions about “Does the battery gasket affect the current Why ”
What happens if a battery is connected in series?
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
How does a battery produce electricity?
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that's what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
What happens if there is a difference between a battery and a wire?
If the difference is small, little/no current will flow. This holds true for any wire connected between any two terminals, anywhere. However, current more than likely won't (depending upon the age/use of the battery).
Why do batteries need to be connected in a circuit?
With this analogy, it is plainly obvious why both the positive and negative ends of a battery must be connected in a circuit. If, say, you connect only the negative electrode to ground, there is no current because there is no electricity coming in on the positive electrode that can be pumped out.
Can a current flow in a battery?
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
What happens if a battery is connected in parallel?
When batteries are connected in parallel, the voltage across each battery remains the same. For instance, if two 6-volt batteries are connected in parallel, the total voltage across the batteries would still be 6 volts. Effects of Parallel Connections on Current
