Meeting 13:
We did circuit analysis with
LabVIEW I, in which we made a Virtual Instrument (VI) that produced the current
I (unit is A for amp) that goes through a resistance R (unit is Ω for Ohm)
when a battery voltage V (unit is V for volt) was applied. The two input
elements (V and R) are implemented with Numeric Controls, and the one output
element (I) is implemented with a Numeric Indicator. Then a Divide operator is
inserted into the Block Diagram, and everthing connected with the Wiring tool.
Logbook
Just to remind that the logbook is a very important component
of the course and will be evaluated, together with the final exam they count
20% of the course grade.
You should record the logbook on a daily basis, with pages
numbered and dated, about two main topics:
-Discussions
and findings about projects, collectively or individually
-Answers
to questions posted here in the class notes and other learning conclusions you
found by doing activities related to this course.
The next logbook due date is
Logbook questions:
1-What is the difference between a Numeric
Control and a Numeric Indicator?
2-Can I wire into a Numeric Control? Can I
wire from a Numeric Control?
3-To implement V/R: should I wire V to the
upper left terminal of the Divide operation or to its lower left terminal? Why?
