Therefore, isc = forty eight mA (from desk) [f] The plot of voltage as opposed to present built partially (a) isn't linear (it is piecewise linear, yet now not linear for all values of is ). because the proposed circuit version is a linear version, it can't be used to foretell the nonlinear habit exhibited by means of the plotted facts. P 2. 18 [a] Write a KCL equation on the best node: −1. five + i1 + i2 = zero so i1 + i2 = 1. five Write a KVL equation round the correct loop: −v1 + v2 + v3 = zero From Ohm’s legislations, v1 = 100i1 , v2 = 150i2 , v3 = 250i2 Substituting, −100i1 + 150i2 + 250i2 = zero so − 100i1 + 400i2 = zero fixing the 2 equations for i1 and i2 at the same time, i1 = 1. 2 A and i2 = zero. three A [b] Write a KVL equation clockwise round the left loop: −vo + v1 = zero So yet v1 = 100i1 = 100(1. 2) = a hundred and twenty V vo = v1 = one hundred twenty V [c] Calculate energy utilizing p = vi for the resource and p = Ri2 for the resistors: psource = −vo(1. five) = −(120)(1. five) = −180 W p100Ω = 1. 22 (100) = one hundred forty four W p150Ω = zero. 32 (150) = thirteen. five W p250Ω = zero. 32 (250) = 22. five W Pdev = a hundred and eighty W Pabs = a hundred and forty four + thirteen. five + 22. five = one hundred eighty W © 2010 Pearson schooling, Inc. , higher Saddle River, NJ.

[c] The voltage drop around the resource is v0, obvious via writing a KVL equation for the left loop. hence, pg = −vo ig = −(16)(0. 01) = −0. a hundred and sixty W = −160 mW. hence the resource supplies one hundred sixty mW. © 2010 Pearson schooling, Inc. , top Saddle River, NJ.
