  • Simple AC power question

    HI

    if i run device with nice AC sine wave

    Voltage = 10 V
    Amperage = 1 A
    Frequency = 50 Hz
    Power factor = 1

    i am feeding it with certain Power...

    if i double frequency but other variables stays the same

    Voltage = 10 V
    Amperage = 1 A
    Frequency = 100 Hz
    Power factor = 1


    Does the input power stays the same or increases or decreases <?

    Thanx

    how it will be in case of ac motor controlled by VFD

    will unloaded ac motor consume same input power when running on 50hz vs 100hz ?
