Do the US also have 240V as well?
Yes, as Refugee says, many domestic supplies are 120-0-120V with lights and normal 120V outlets connected between one hot and neutral, while high-load appliances such as tumble dryers and large air-conditioners run at 240V between the outers. Electronic goods are almost always 120V (historically 110 or 115V) as 240V outlets are normally only provided where the load justifies them.
