Hi to all,
I used to be a member here a few years back and have decided to sign back up now i have a computer again!
My current problem is that whilst i understand the concept of phase rotation,i am failing to see how the below link demonstrates identification of phase rotation with "scewing the current and voltage".
Any help is much appreciated.
ps is there any half decent free electrical simulation programs that anyone knows of,i have used p spice but i think that is more of an electronic program.
