This attempt took 6 minutes.
The weekly lab quiz is due Friday midnight of the respective week. However, as much as possible,
you should try to do the quiz before your lab section. You definitely need to read and understand the
materials before the beginning of your section; otherwise you risk not being able to finish your lab
exercises which will lead to a lower lab report score. If you have questions about grading or mistakes in the quiz, contact your Instructor and/or TAs.
NOTE: In this Quiz, you will have THREE
Attempts.

Question 1
Answer 1:
Answer 2:
DC versus AC problem. Suppose your DC power supply is set to 15 V
and the vertical setting on the oscilloscope is at 5 V/div. How many
divisions will the trace deflect if you connect the output of the power
supply to the scope with the "A input" switch set on DC? How many
divisions if the switch is on AC? Please write your answer with integer
values.
3
divisions for DC, 0
divisions for
AC,

Question 2
Maximum current problem. If the current on your power supply exceeds
500 mA it can damage the supply. Suppose the supply is set for 37 V.
What is the smallest resistance you can measure? Please round your
answer to the nearest integer.
