In an experiment, values of two resistances are measured to be r1 = (5.0+-0.2) ohm and r2= (10.0+- 0.1) ohm. Find the values of total resistances in parallel with limits of percentage error.

Dear Anupam,

Parallel equivalent is 10/3 ohms and the error percentage is simply added i.e. 3.33+-0.3 ohm.

Best Of luck

Plz Approve the answer...!!!!
