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

213 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.

Your battery has 10V of voltage, not power. Simplified, until you reach the limit of what your battery can deliver in terms of current, it will hold the voltage at (more like close to) 10V. If you connect the first load (i wouldn’t just say wire, because that would suggest you’re short-circuiting the battery), then a current will flow that is defined by the voltage of the battery and the resistance of the load. Let’s assume the resulting current is way within the limits of the battery. The second load you connect will still see the same 10V, and again the load defines how much current will flow, if all loads combined are still not overloading the battery.

And yes, your guess is correct that with two identical loads connected, the battery will discharge at double the rate as if it was only connected to one of those loads.
