Answer / supriya

In electronics, the form factor of an alternating current
waveform (signal) is the ratio of the RMS (Root Mean
Square) value to the average value (mathematical mean of
absolute values of all points on the waveform).
i.e.
Kf=RMS/AVERAGE

Answer / viendra

Form Factor = RMS Value / Average Value

Answer / ganesan govardhan

Hi,I am Ganesan Govardhan
Significance of form factor:
When an AC voltage is rectified by a full wave
rectifier,the DC value equals the Average value.
Having given the RMS AC input,we can find the DC output
from the relation

Edc = Erms/Form factor

Answer / dany

SUPRIYA, it is a good answer ,but can u clarify what is the
significance of this form factor

Answer / ponnu(the elite)

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
