Problem Set #28
Q3. Consider the two circuits: series vs parallel as shown below, where R2 > R1. The
symbol with the curved line is for an AC power supply (outlet).
, 120 Vac
Series
Brighter = more power, P = IV. Thus we need to compare the current

We have looked at two sources of voltage = avg electric potential energy or
ways to produce electric elds essentially inside conductors to make charges
move and thereby create current:
