"For the currents and voltages in the problems below, provide theabsolute values only, ignoring the sign". Given that Is1 is 13 A,R1 is 59 Ohm, R2 is 17 Ohm, R3 is 8 Ohm, R4 is 2 Ohm and Is2 is 5A.
(A)
Find the value of "v1". (Unit: V)
Tries 0/3
(B)
Find the value of v2. (Unit:V)
Tries 0/3
(C)
Find the value of i1. (Unit:A)
Tries 0/3


Would you want to approach this using the nodal analysis Matrixtechnique? I'm too scared to try otherwise since I really won'tknow until I use up all of my tries and won't get credit for thisproblem on my homework.
Tries 0/3

Explanation / Answer

we are going to use nodal analysis approach: top left node: v1 top right node: v2 ................ (v2 = v1 - 8i1) kcl @ v1: -13 + v1/59 + v1/17 +i1 = 0 13039 = 76v1 + 1003i1 kcl @ v1 - 8i1: 5 + (v1 - 8i)/2 - 2i1 = 0 v1 = 10i1 - 10 plug in v1 into first equation: i1 = 7.827 plug this into v1: v1 = 68.27v plug this into v2 = v1 - 8i1: v2 = 5.654v THANK YOU AND PLEASE RATE
