Answer / prasant

for dc average value,rms value and maximum value is same,so
the form factor is unity.

Answer / akash kumar

form factor= rms/avg
for DC rms=avg
therefore FF=1

Answer / mukhesh

ther is no form factor in dc f f is ratio of rms value
and avg value
rms only in ac means max value in dc avg value taken

Answer / dhaval

in ac always form factor is 1.414 it is ratio of rms value
and average value buat in dc no rms value then dc form
factor is 0

Answer / sathish

The Form factor of DC is always infinite.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
