Name : g0 If“; ECE Box Number: , / Problem 1: Finding the Thevenin and Norton equivalent of simple circuits Solve the following problems by ﬁnding the Thevenin and Norton equivalent of of each network at
the terminals. You should do this by ﬁrst ﬁnding the short circuit current isc and the open circuit
voltage vac. In this problem you will show the most important steps of this process by writing out the equa
tions that you will solve, then the answers. Please write the equations in a completely unsimpliﬁed
form, i.e., exactly as would read the equations off the circuit applying the basic principles of nodal
analysis and not combining any of the values in each equation. Place your numerical answers on the lines provided to clearly identify the six values: isc, vac,
W, 12TH, RN and RTH. Following the two above rules will greatly reduce the effort and increase the
accuracy of grading. Thankyou. of 75 3:0 I

Use Nodal analysis with the indicated ground as the reference. The ﬁrst step in dependent source
analysis involves expressing the contolled source’s value (of voltage or current) in terms of the
named nodal voltages and other circuit component values  Show in the space provided
(ﬁrst in the list) what that equation is in each case. The only variables that appear in the nodal
equations should be the nodal voltages named in the circuit diagram — no other variables. Then
show the nodal equations that can be used to solve the circuit and the numerical answer. w 5Q (c3 :qu 5 («X 7
