    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
    please check me

    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.
