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].
