Networks Analysis and Synthesis
13.
In the circuit of figure, the power consumed in resistance R is measured when one source is acting at one time. These values are 18 W, 50 W and 98 W. When all source act together the maximum and minimum power can be
98 W and 18 W
166 W and 18 W
450 W and 2 W
166 W and 2 W
Answer: Option
Explanation:

Let R = 1 Ω.

Then I1 = 32 A, I2 = 52 A and I3 = 72 A.

(I1 + I2 + I3)2 R = (152)2 R = 450 Ω.
