Electrical Engineering Interview Questions

What is the current carring capacity of 0000SWG and 0SWG overhead solid bare copper conductor. If possible please provide reference for various sizes Vs current ratings

3044

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?
