One 200 V, 100 W bulb is connected in series with primary of
a 200 V, 10 kVA transformer. If its secondary is
kept open circuited, then the bulb would have
(1) Full brightness (2) Poor brightness
(3) A little less than full brightness (4) More than full
As we use capacitor bank in 3ph ckt to improve PF,
can we use capacitor in single ph domestric use,
in house we have Fan,Mixer,electric cooker,iron,tube choke
they also lag the system,because it is inductive load.
if it is possible to improve PF of single ph system--
if yes- type of capacitor to be used,connection diagram,
working in detail.
if no-- list it.
As we use capacitior bank in 3ph ckt for improvement of PF,
why not we use capacitor in single phase domestric use, at
house their are many inductive equipments,like
fan,mixer,tube choke,air conditioner they also draw PF...
by using capacitor can they improve PF.
if yes--what are advantage and how to connect a capactor
in single ph,and which type of capacitor
if no- what are disadvantages.
What is the role of Dedicated earthing in UPS System?
why actual valve timing diagram is different than ideal
valve timing digram of a 4 stroke engine?
we can run 2phase as 3phase .what will be the
differnce with respect to phase angle, power, current
between the two modes
How much earthing frequency is capable?
does the Trivector Meter of three phase automatically takes
care of the low power factor and gives the reading
accordigly or it does not take care of the Power factor
while giving the readings please explain
