Network Analysis (70A)
Complains/inquiries : You have 1 week from the time you receive your homework or exam to identify
omissions or incorrect grading. After one week your paper will no longer be considered for re-grading.
Final Examination: The final examination will be from all the course material covered but
mostly will focus on the material covered after the midterm. A missed final will be dealt with
according to the university regulations on incompletes and withdrawals.
will be absolutely NO "make-up" exams. In case you miss a mid-term for reasons beyond your
control, weight of the mid-term will be added to the final examination.
Midterm: There will be one mid-term examination, carrying 30% weight. Please note that there
Quizzes: Short quizzes will be given weekly to make sure that you stay abreast with the lectures.
There will be absolutely NO "make-up" quiz. However, one quiz with the lowest score will be
dropped.
Homework: Homework for practicing the concepts learned in the lectures will be assigned on a
weekly basis with few exceptions. Homework are typically assigned on Thursday and due the
following Thursday. Late work will not be accepted and makeup homework will not be
assigned.

Student A is responsible for lab report for Experiment 1
Student B is responsible for the lab report for Experiment 2
Student C is responsible for lab report for Experiment 3
The rotation then repeats, so Student A is responsible for Experiment 4, and so on
By the end of the quarter, each student will be responsible for three lab reports and 9 prelabs.
Although report responsibilities rotate, all group members are expected to actively participate in
every experiment and remain fully aware of the procedures and concepts involved at all times. Student
preparedness and participation will be randomly assessed by the teaching assistant throughout the
quarter. These assessments collectively account for 25% of the final course grade.

Group Size and Responsibilities
Students must work with their assigned lab partners during each laboratory session. Each group may
consist of a maximum of three students.
Responsibility for lab reports will rotate among group members while each member is responsible for
the prelab for every experiment. For example, in a group of three students (A, B, and C):
Lab 9, week 9: Complex power
Covered topics:
Lab 1, week 1: Lab orientation
Lab 2, week 2: Ohms law and basic I-V curves
Lab 3, week 3: Resistor networks, Power
Lab 4, week 4: Network analysis KCL and KVL
Lab 5, week 5: Thevenin, Northon, superposition
Lab 6, week 6: AC signals basic AC circuits
Lab 7, week 7: Impedance networks
Lab 8, week 8: Impedance networks and phasors
Lab content and related materials:
Lab notes with experiments will be posted on line every week, there is no official text book for this
laboratory, but all the theory is covered in EECS70A, the text book used for 70A is:

2. Laboratory Skills and Ability
Students are required to demonstrate proficiency in the effective use of laboratory equipment. This
includes, but is not limited to, the proper operation of the oscilloscope, power supply, signal generator,
and other lab instruments. As part of the lab ability assessment, students may be asked to perform
additional experimental steps and explain or comment on any observed phenomena. Each week, the TA
will evaluate a different group member to ensure that all students demonstrate individual competency
throughout the quarter.
1. Pre-Lab Reports and Lab Grades
Pre-lab assignments will be checked by the Teaching Assistant (TA) at the beginning of each lab session.
To receive credit for a lab, all collected data must be reviewed and approved by a TA before you leave the
laboratory. Please do not disassemble your circuits until this data review has been completed. Postprocessing of experimental data is an essential component of the final grade. Students are expected to
present their results clearly and comprehensively in a properly formatted lab report. The quality of data
analysis, presentation, and discussion will be reflected in the final lab grade. Lab reports are due the
following week. The late submission policy for lab reports is the same as the late homework policy.

Current sign convention
• An ideal voltage source has no internal
resistance.
• It also is capable of producing any amount of
current needed to establish the desired
voltage at its terminals.
• Thus we can know the voltage at its terminals,
but we don’t know in advance the current.
Ideal Voltage Source
• Current sources are the opposite of the
voltage source:
• They have infinite resistance
• They will generate any voltage to establish the
desired current through them.
• We can know the current through them in
advance, but not the voltage.
Ideal Current Source
• Both the voltage and current source ideally
can generate infinite power.
• They are also capable of absorbing power
from the circuit.
• It is important to remember that these
sources do have limits in reality:
• Voltage sources have an upper current limit.
• Current sources have an upper voltage limit.
