1.	Consider a circuit having resistances 16 Ω and 30 Ωis excited by a voltage V. A variable resistance R is connected across the 16 Ω resistance. The power dissipated in 30 Ω resistance will be maximum when value of R is __________(a) 30 Ω(b) 16 Ω(c) 9 Ω(d) 0I got this question in quiz.My question is based upon Series-Parallel Interconnection of Two Port Network topic in division Two-Port Networks of Network Theory
Answer» Correct answer is (C) 9 Ω The EXPLANATION is: We KNOW that, When R = 0, circuit current = \(\frac{V}{30}\) A And Power dissipated = \(\frac{V^2}{30}\) Watts. This is the maximum possible value which occurs for R = 0 Ω.
