Step-by-Step Verified Solution

Equivalent resistance of upper branch of circuit R = 2.5 Ω\Omega JEE Main 2020 (Online) 7th January Morning Slot Physics - Current Electricity Question 229 English Explanation 1

Voltage across upper branch = 1 V

∴\therefore i1 = 12.5{1 \over {2.5}} = 0.4 A JEE Main 2020 (Online) 7th January Morning Slot Physics - Current Electricity Question 229 English Explanation 2

i = 0.42{{0.4} \over 2} = 0.2 A
