I put site:eletricalandelectronics.com into Google and it showed over 250 results, so I think the site it being indexed fine. Google aren't going to fully index a new, low-traffic site in just 2 weeks, there are trillions of other sites they need to index too.
I also noticed that several of your questions have an image as the answer instead of text. Search engines can't read the text in images, you should put regular text in the answers and have just the diagrams as pictures.
