Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Reduce the circuit using symmetry and series–parallel combinations.
Step 2: Find the equivalent resistance of each section and the total current drawn from the battery.
Step 3: Apply current division to the branch containing the 3Ω resistor.
Step 4: The current through the 3Ω resistor comes out to be 0.25A.
