- \( \dfrac{1}{10}\,\text{A} \)
- \( \dfrac{3}{10}\,\text{A} \)
- \( \dfrac{4}{10}\,\text{A} \)
- (7)/(10)A
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Equivalent resistance of the network: Rₑq = (20)/(3)Ω
Step 2: Current: I = fracVRₑq = (2)/(20/3) = (3)/(10)A
