My Dental Practicum rotation was a fulfilling experience where I achieved my objectives, primarily focusing on patient interaction and dental procedures. I would aim for more complex procedure exposure in future rotations and recognized the importance of effective patient communication. Overall, I enjoyed my time and look forward to a similar role in the future. ;
In a device delivering a current of 15.0 A for 30 seconds, the total charge is 450 C. Using the charge of an electron (approximately 1.6 x 10^{-19} C), we find that about 2.81 x 10^{21} electrons flow through the device during this time. Thus, around 2.81 billion billion electrons are involved in the current flow.
