NEET Solved Paper 2017 Question 15

Question: Figure shows a circuit contains three identical resistors with resistance $ R=9.0,\Omega $ each, two identical inductors with inductance L = 2.0 mH each, and an ideal battery with emf $ \varepsilon =18,V. $ The current ‘i’ through the battery just after the switch closed is

Options:

A) 0 ampere

B) 2 mA

C) 0.2 A

D) 2 A

Show Answer

Answer:

Correct Answer: D

Solution:

At t = 0, no current flows through $ R _1 $ and $ R _3 $ $ i=\frac{\varepsilon }{R _2} $ $ =\frac{18}{9} $ $ =2A $

Note: Not correctly framed but the best option out of given is [d].
