1) In the following network, the current flowing through 15Ω resistance is A) 0.8 A B) 1.0 A C) 1.2 A D) 1.4 A Answer: Option CExplanation: The above circuit is a balanced Wheatstone bridge. Hence, the above circuit is drawn in the following manner From the above circuit, 18 l=24(21-l) 18 l= 50.4-24 l 24 l+18l=50.4 42 l=50.4 l = 50.442 ∴ l= 1.2 A
