JEE Main 2020 (Online) 9th January Morning Slot Physics - Current Electricity Question 223 English Explanation 3

I = $${{20} \over 2}$$ = 10 A JEE Main 2020 (Online) 9th January Morning Slot Physics - Current Electricity Question 223 English Explanation 4

I₁ = $${4 \over 5}I$$, I₂ = $${1 \over 5}I$$

$$ \Rightarrow $$ I₁ = 8A, I₂ = 2 A

I₁' = $${3 \over 5} \times 10$$ = 6 A

I₂' = $${2 \over 5} \times 10$$ = 4 A

$$ \Rightarrow $$ I_BC = 8 – 6 = 2 A
