Figure shows a circuit that contains three identical resistors with reisistance `R=9.0 Omega` each, two identical inductors with inductance `L=2.0mH` each, and an ideal battery with `emf e= 18V`. The current I through th battery just after the switch closed is

A

2 mA

B

0.2 A

C

2A

D

0 ampere

Text Solution

Verified by Experts

The correct Answer is:
C

At =0 , no current flows through `R_(1) and R_(3)`

`i=(epsi)/(R_(2))`
`=(18)/(9)`
`=2A`
Note : Not correctly framed but the best option but of given is (3).
