1 L V nAu nAuE i Δ = = L L i i 2 1 2 > Electron mobility in metals decreases as temperature increases! Conversely, electron mobility in metals increases as temperature decreases. Thus, the current in the 2-bulb circuit is slightly more than that in the one-bulb circuit. Two Identical Light Bulbs in Series Identical light bulbs Two identical light bulbs in series are the same as one light bulb with twice as long a filament. Lecture 16 Chapter 20. Capacitors, Resistors and Batteries Announcement: There will be no lectures on Monday March 28 and Wednesday March 30, 2011 to compensate for the two evening exams: Exam #1 that took place on Feb 15 th , 2011 Exam #2 that will take place on March 30 st , 2010.
