Question

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) 0 I got this question in quiz.

Answer 1

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.
