Why electric current doesn’t decrease for each wire i connect to a battery?

211 views

For example, if i have a battery with 10V of power, and then i connect a wire to the battery it will have 10A of current in it.

If i connect 2 wires, why current doesn’t split between the two wires so that i have 5A in each one?

I have no knowledge in this area, the only logical conclusion i can come to with the little information i have is that both wires will have 10A of current because both will “work at full potential”, but then, the battery will run out of power at double the speed compared to having only 1 wire connected.

Is my guess correct or the solution is another one?

Thanks in advance.

Power is voltage multiplied by current. 10V will get you 10A across a 1 ohm load. That would be 100 watts. If you have two such 1 ohm loads and put them in parallel, the current drawn and power used will double. If you put them in series, the voltage across each of them will be 5v, and the current will be cut in half, so the overall power will be cut in half.

If you short circuit a battery, you only have the internal resistance of the battery, and the resistance of the wire itself to limit current, depending on how much energy the battery stores, this can be dangerous.
