why do we measure VIBRATION in -24vdc and why we adjust gap voltage -9vdc to 10-vdc? i am trying to get this information since 5 years, yet i haven't get reliable answer, i hope i can get from you.
Describe the method of Plate Earthing.
In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
