Answer / ragavan
1. the power factor of a purely inductive load is zero.
because the phase angle between voltage and current is 90
degree electrical. hence power factor is zero.
2. in general star/star connection is used. this is
neutral terminal can be easily accessible both on hv and lv.

On monitor it is written that current rating is 2.2 Amps. Is it a monitor current drawing capacity or CPU & monitor. If it is only monitor rating, what will be the rating of only CPU and what will be the power consumption rating of PC, Monitor & Scanner? In net, I learnt that computer consumes only 200-300W while running. With the current rating of 2.2 Amps, how it could be 200-300Watts. Please explain?
Why are transmission lines multiples of 11? Is it because of some historic reason ? Or is there a scientific base to it?
