3/10/03, Minute Paper. You have to slow down and show all your steps…If they are messy & hard & you skip over them, how do you expect us to be able to do? If I, hypothetically of course, were to get 25 points out of 100 on my homework, does that mean I’m going to fail the course?

  1. 3/10/03, Minute Paper • You have to slow down and show all your steps…If they are messy & hard & you skip over them, how do you expect us to be able to do? • If I, hypothetically of course, were to get 25 points out of 100 on my homework, does that mean I’m going to fail the course? • Is there a easier way to do ac circuit analysis? • Set of office hours? • Lab data and graphs have to be clearly presented in the report. Not just raw data sheet! • 1:30 meeting

The larger the RC, the longer it takes to charge a capacitor. The larger the R value, the smaller the current is in the circuit. The larger the C value, the more the charge the capacitor can hold
