    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
