Here is a question to make you think.
How much electrical theory should a first year apprentice know?
Not so much on the job stuff but classroom work.
Now that I am in a teaching post I am having to re-learn a lot of stuff. Stuff that I just took for granted whilst on the tools (never looked at once on the tools more like, or just did without thinking about it)
I have been asked to look at the units I teach with a view to improving them. Ohms law , Kirchofs law, series and parralel circits are quite staight foward. But the only way I see of taking these units froward is to introduce more AC theory.
Is it usefull to know how to calculate RMS, peak and average voltages,complex numbers, phase angles and the like?
Shurely only a systems designer is concened about these calculations? Or do you use them out in the field?????
