Considerations
Saving file in 640X480 from 720X480 did not result in any appreciable
loss of image, though it might be hard to discern details at smaller image
sizes. Saving for broadband resulted in slightly larger file than in other
formats like ISDN or 56K.
Further work
An interactive demonstration of resitor colour band interpretation may
be useful addition.
AVI or Quicktime files may be useful saved on CD, DVD or video tape. A
collection of short video illustrating all measurement procedures (i.e.
current, capacitance, inductance, etc.) would be useful as a teaching
resource in electronics.

Students
of technology or science may at some point need reinforcement of the
procedure of setting up a multimeter to measure resistor values and/or
resistance of components. Short video clips may be useful for introducing
the concepts and procedures to novices, to reinforce procedures on
an ad-hoc basis or as quiz answers. Useful for technology or science
courses. Next >> |
