hello i am basic confuse

the voltage source that produce 240v ac waveform with 60hz
Time period- 1/frequency =16.67 ms
16.67ms is time taken for 240v ac waveform to complete one cycle
frequency-1/time period=60hz
240v ac waveform has period of 16.67ms with 60 hz
instantaneous value of voltage-after 3 seconds
V=Vmax sin(2πft)
V=(-224.74) volts

my questions
voltage is varied continusly with time
what is maximum time period of signal until the signal is destroyed?
can i measure voltage for 1 hours , 1 day 1monthes?

A sine wave is, by definition continuous, so in theory it goes on forever. It doesn't make any difference how long you take to measure it.
