WebAug 30, 2024 · The change in sign reflects that different sign convention we use for generators and for passive elements. (R1 I1 - emf1) + (R2 I2 - emf2) + ... + (Rn In - emfn) = 0. This is the modern equivalent form of KVL as Kirchhoff formulated it. WebE1 At the top node we have iR = is = 2A. By Ohm’s law we have vR = RiR = 80 V. By KVL we have vs = vR = 80 V. Then ps = -vsis = -160 W (the minus sign is due to the fact that the references for vs and is are opposite to the passive sign configuration). Also we have PR vRiR 160 W. P1. 5 5 6
