Thomas Edison believed it was dangerous to fool around with alternating currents and promoted the use of direct current instead. He was in a bitter rivalry with Nikola Tesla, who championed the use of alternating current for its efficiency over long distances.

How do currents affect?
Warm currents have a very obvious affect on the temperature that surrounds it. Warm currents will warm the area around the currents.

What carries cold and warm ocean water around the world?
Currents
Do electric currents create magnetic fields?
yes. If current is flowing through a wire, the magnetic field is around the wire, like your fingers would be around the wire if you gripped it. If the current was alternating (AC) the field would collapse and expand in time with the alternations. One of nature's mysteries - to me anyway.
When is surfing dangerous?
It's dangerous when: * There is wildlife around (e.g. SHARKS!!!!!) * It is too crowded at the break * Nobody is obeying the surf rules * The waves are too big (this only applies for beginner surfers, but it can also apply for casual surfers) * If there are dangerous rips or ocean currents * When you wipe out badly * When you get cleaned up
Are depressants more dangerous than stimulants?
Most types of alcohol are depressants while most drugs are stimulants. It is generally believed that depressants are not more dangerous than stimulants and that it is, in fact, the other way around.
What happens to the currents in a circuit?
a cell pushes electric currents around a circuit.If there are two or more cells then more currents will flow through them.
What is the conclusion in alternating current and measurement?
The only thing that can be concluded about alternating current is that it alternated at 50 or 60 Hz throughout the grids around the world.
Why was the alternating current motor so important?
Alternating current is very important because the whole worlds uses it and it is the best method to transmit electricity around.
What are the two ocean currents?
Gyre and the Atlantic current and that's all I know but there are a lot of currents around the world
The direction that the Earth's core spin is believed to be the source of its what?
The direction of the Earth's core spin is believed to be the source of its magnetic field. The movement of molten iron and nickel in the outer core generates electric currents, which in turn create a magnetic field that extends around the planet and protects it from solar radiation.
What is the region where both winds and ocean currents flow unimpeded around the world is?
