Spring 2016-2017 Quiz I

Instructor: Mohammad N. Sabet

Q1. In the following circuit , use Nodal analysis to find the currents ,

20 V 1 A+- 10 Ω 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= Vx

10

v=20 v
