Answer & Solution

Correct Answer

(B) 21

Step-by-step Solution

Detailed explanation

\(6i_{1} + 3(2i_{1} - i) = 3(i - i_{1})\) \(\Rightarrow 15i_{1} = 6i \Rightarrow i_{1} = \frac{2}{5}i\)\(\quad\) ___(1) \(3(i - i_{1}) + 6i_{1} = 1\) \(3i + 3i_{1} = 1\) \(\Rightarrow i =\frac{5}{21} A=\frac{1 V}{ R _{ eq }} \Rightarrow R _{ eq }=\frac{21}{5} \Omega\)
