Billions In The Blink Of An Eye

A 60-Watt light bulb is connected to a 120 V outlet. How long in seconds does it take for 1 billion (10910^{9}) electrons to pass through the light bulb?

Details and assumptions

  • The charge of the electron is e=1.6×1019 Ce=1.6\times 10^{-19}~\mbox{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.
