Batteries with 0 resistance in parallel

What would happen in a circuit like this, both theoretically and in real life?

Would the voltage difference across the points A and B be

  • 1V
  • 2V
  • something in between 1V and 2V?

Any insight for a circuit like this would be helpful.

Thanks!

Clarification

Two batteries of 1V and 2V are connected in parallel with a 1ohm resistor.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

You need to consider the internal resistances of the batteries in situations like this. If you draw each battery as an emf and a resistor in series you will be able to get a consistent solution for the current and voltages via Kirchhoff's laws.

I had the same doubt some time ago... Our professor told us that the properties of batteries themselves will change making them incapable of maintaining the potential difference they were made for. I don't know how. I'm not really sure that this happens too. Can someone help us out?
