Physics Question on Alternating current
Three identical resistors with resistance R=12Ω and two identical inductors with self inductance L =5mH are connected to an ideal battery with emf of 12V as shown in figure. The current through the battery long after the switch has been closed will be ______A.
Answer
The correct answer is 3.
After long time an inductor behaves as a resistance-less path.
So current through cell
I=R/312=3A{∵R=12Ω}
