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?

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
