Final Exam
Report:
1.
2.
3.
Every lab must contain a lab report performed by each student individually.
The lab report must contain the rough data sheet of the lab signed by the lab instructor.
If any report is found copied from another, then both lab reports will be cancelled.
Guidelines on Report Writing:
The lab report must contain the following parts:

Cover Page: The cover page will contain name of the university, name of the semester, course id, section,
student name, student id, Experiment no, Experiment name, date of experiment and date of submission.

Objective

Apparatus: A list of the equipments used in the experiment.

Circuit Diagram

Experimental data: This part will contain the experimental data taken in the class (signed by the
instructor).

Calculation: This part will contain all the experimental & theoretical calculations in detail

Graph (If any)

Conclusion: what was found or verified.

Discussion: An explanation and analysis of the lab data which links the objective to the conclusion. This
part will contain data analysis, graph analysis, result analysis, comparison between theoretical results
and experimental results.

Precautions & Answers of the Questions (if any)
Important Safety Notice:

Don't ever put your finger on a resistor "to see if it's hot". If it is hot, you'll burn yourself. Note: resistors never
"look" hot, so just don't touch one when it's in a circuit.

Don't touch any part of the circuit while the current's flowing or when the DC power supply is on. You may
think it's safe and you know what you're doing. Assume it's not safe and you could have made a mistake. Turn
the power off first.

Items such as books and jackets should not be left on top of the test equipment as it could cause overheating.

When the multimeter is in ammeter mode, it goes in series. Not parallel. You can ruin the ammeter if you put it
in parallel.
Disciplinary Steps:

No food or drink is allowed in lab at any time. Liquids are of particular danger as they are
ordinarily conductive.

Your work area and common areas must be clean before you leave the lab.
