Route 7.
Getting Emolga in White version is the same as getting Emolga in Black version. The easiest way is to catch a Boldore and bring it to the first house you see on the route north of Mistralton city. There's a hiker in the house who will trade you his Emolga for a Boldore. If you don't want to have an Emolga with a nickname that you can't change (since any Pokemon received through in-game trade has a nickname) then you can breed the hiker's Emolga with a Ditto (since the Emolga is a male) and then hatch the egg, like I did. Or instead of trading for the hiker's Emolga, you can go and catch one in the wild. Emolga is only found in shaking grass spots everywhere you find wild Pokemon except for the area between Nimbasa city and Nuvema town. However, you're gonna have to be patient since not only are shaking grass spots uncommon, but your chance of finding an Emolga in one of those spots is usually 1/10. Best of luck, though.
