A 60-Watt light bulb is connected to a 120 V outlet. How long in seconds does it take for 1 billion (109) electrons to pass through the light bulb?
Details and assumptions
- The charge of the electron is e=1.6×10−19 C.
- You may consider the voltage as a constant voltage source. The time you will find is short enough that the fact that wall outlets generally deliver alternating voltages can be ignored.
