Could you please help me calculate the branch current? Thanks!

The current of R1 can be obtained by directly dividing the battery voltage by R1. The other two calculations are more complicated, but not difficult. You can list a set of multivariate linear equations and solve them.

I'll use a stupid method

I0= 6.8mA

The current flowing through R1 is 5mA

Then, the formula is obtained by fitting the data using different combinations of multiple resistors.
