Subtransmission is part of an electric power transmission system that runs at relatively lower voltages. It is uneconomical to connect all distribution substations to the high main transmission voltage, because the equipment is larger and more expensive.
First, espresso is the coffee that makes a cappuccino and latte. Espresso is a strong, bitter, and concentrated coffee. Itâs usually consumed in shot glass quantities, often mixed with steam milk, foam, etc. That brings me to part two. A latte is espresso and steamed milk with a small layer of milk foam on top. A cappuccino is the same but with a smaller amount of steamed milk and a larger layer of foam. Usually a cappuccino has a 50/50 milk to foam ratio. Also, I wrote an article expanding on this.
One of the major differences from espresso is to add a sprinkle of cinnamon or cocoa powder to the cappuccino. Cappuccino is not just a mixture of steamed milk and espresso as you can make many varieties of this beverage.
