Laboratory notes will be distributed in
class
Grading: Lab
notebook 40%
All experiments reported in your notebook,
except the write-ups (see below)
Each report should contain:
Abstract (what is the topic about,
the main measurement you made, the main
result) No more than ~ 5 lines; Background, Equipment, Procedure
and
Conclusion sections
Good presentation expected, clear, readable, neat (make a good use of your
ruler
when making your tables and circuit diagrams.) Use scientific notation
(i. e. 1.2 x 10-3 Volts)
Estimate the precision of your measurements;
i. e. x = (7.1 ± 0.05)x10-3 cm
Report write-ups 30%
Out of the last 9 experiments listed below, write-up papers of 2 selected
experiments
(#4 and #6) are required. Submit them in hard copy and electronic formats.
A write-up paper sample (on Exp #1) will be provided in class (use it as
a guidance.)
Search assignment:
15%
Choose one of the following two topics:
a) Fabrication methods of Resistors and Capacitors: Types, noise
considerations.
b) Batteries: Working principle, types, comparison of noise level
with other DC power
supplies.
Work performance during laboratory session: 15%
Read lab notes ahead of time.
Positive attitude toward completing your tasks
Follow guideline to prevent equipment damage (i.e. make sure power supplies
are in
its lowest output values before turning them on)
Estimate the precision of the equipment used.
