JEE Mains · Physics · STD 12 -6. Electromagnetic induction
Three identical resistors with resistance \(R=12 \Omega\) and two identical inductors with sell inductance \(L=5 mH\) are connected to an ideal battery with emf of 12 V as shown in figure. The current through the battery long after the switch has been closed will be _________ A.
- A 1A
- B 3A
- C 5A
- D 7A
Answer & Solution
Correct Answer
(B) 3A
Step-by-step Solution
Detailed explanation
After long time an inductor behaves as a resistance-less path. So current through cell \(I =\frac{12}{ R / 3}=3 A\{\because R =12 \Omega\}\)
