EENG 225 Fundamentals of Electrical Engineering
Spring 2016-2017 Quiz I
Instructor: Mohammad N. Sabet
Q1. In the following circuit , use Nodal analysis to find the currents ,
5
20 V 1 A+- 10 i2
i1
Q1
T 100
Time: 9.30-10.00
Vx
Apply KCL at node Vx , assuming all currents are leaving the node(You can do this by redrawing the circuit and temporarily ignore all the unknown to proceed with the analysis)
(Vx-20) 5
+Vx10 -
1=0
Vx=16.6 V
From the original circuit and given current directions:
i1=(20-Vx)
5*: Be carefull on current direction
i2= Vx10
v=20 v
