Welcome to PH 411. A practical electronics course from the physicist's viewpoint. We want to understand the physics that drive the circuits you build.

12/15 - Thank you all for all your excellent contributions, and complex circuits constructed and analyzed this term. [web content available upon request]

Course materials: Course materials except for Lab Demo Videos (see menu above) are posted here at http://sites.science.oregonstate.edu/~grahamat/COURSES/ph411/ (this course site is also mirrored on CANVAS).
Some reports consist of figures and captions only (see guidelines under each assignment in CANVAS). Others require more complete write-ups, see the writing resource link above and the lab report summary (.pdf).

Course Work:

Daily lab work is posted on the main course web site: http://physics.oregonstate.edu/~grahamat/COURSES/ph411/
Each assignment is a laboratory activity to be completed over several class sessions.
A brief report for each assignment is required.
Each report will be graded out of 20-30 points possible. Important aspects are completeness, documentation of procedure and results, and experimental skill.
For some activities, you will work in pairs, but each student must submit a separate report.

Optional: You may wish to buy a SECOND digital multimeter (DMM)-- you'll actually NEED two meters every class, we recommed DMM #1.
Everyone will get 1 multimeter to keep thanks to AstroAI for supporting Electronics at Oregon State, Physics.

Additonal DMMs will also be provided at no cost to everyone, but are for use within the electronics lab only. Most folk will just use your partner's DMM.
