How do I find the current in this parallel circuit?

Hardware design

As shown in the figure, I can calculate that I1 is 5A, but I am not too sure about I2. I’m just learning about electronics, and I hope you can help me a lot, thank you

This is too simple, look at the potential difference between the two ends of R2.

Obviously R2 is in a short circuit state.

In the closed loop of R1, there is a voltage difference of 10V across R1, and the current I1 = 10/2 = 5A.

In the closed loop of R2, there is no voltage difference across R2, and the current I2=0.

After the two ends of R2 are short-circuited, they are only connected to the R1 loop, and there is no parallel connection.
