How long does it take the voltage to go from zero to maximum on a 60 Hz power line?

The voltage on a utility power line, graphed against time, is the shape of a nice,

smooth sine function. At 60 Hz, it goes through 60 complete wiggles every second.

So it rises from zero to maximum in 1/4 of 1/60th of a second =

1/240 = 0.004167 second (rounded)

That's 4 1/6 milliseconds
