- \(4\,\text{A}\)
- \(2.5\,\text{A}\)
- \(2\,\text{A}\)
- None of these
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Reduce the network using symmetry and series–parallel combinations.
Step 2: Equivalent resistance of the network is 72Ω.
Step 3: Total current: I = (180)/(72) = 2.5A
