Why is it electrical power is normally transmitted at high voltage?

User Avatar

Asked by Wiki User

Simplistically Power is Voltage times Current. Sending at domestic voltage requires much more current to be sent for the same power and therefore much thicker wires, heavier equipment and more repeater transformers as over distance the resistance of the wires and switches would cause the voltage to fall quickly below domestic. For the same power delivery, sending at higher voltages requires less current, lighter wires, and voltage losses over distance are more easily managed so much less equipment is required.

What are the disadvantages of ocean?

User Avatar

Asked by Wiki User

If treated with respect there are no real disadvantages. If you live near the beach like I do then a disadvantage is beach erosion, hurricanes, salt corrosion, seagull poo. If you are out on the ocean in a little boat and a storm comes up then you are at a disadvantage. However most of the disadvantages are because we put ourselves in a position that we shouldn't be in. One thing I heard was that when we go swimming in the ocean we become part of the food chain.

Why do you need more energy when you get older?

User Avatar

Asked by Wiki User

As we age, our metabolism slows down, leading to a decrease in the amount of energy our body can produce from the food we eat. This can result in feeling more fatigued and needing more energy to perform daily activities. Additionally, factors such as reduced muscle mass, hormonal changes, and chronic health conditions can also contribute to the increased need for energy as we get older.
