JEE Main 6 April 2026, Shift 2, Physics Q49

Question 49 of 75 in this shift, Physics question 24 of 25, Section B.

Two cells of emfs 1 V and 2 V and internal resistance 2 Ω\Omega and 1 Ω\Omega, respectively connected in parallel, gave a current of 1 A through an external resistance. If the polarity of one cell is reversed, then value of current through the external resistance will be α5\frac{\alpha}{5} A. The value of α\alpha is __________.
