EENG 225 Fundamentals of Electrical Engineering

Spring 2016-2017 Quiz I

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
