How Does Electricity Work?

There’s an old saying that says “No one cares how it works, just that it works.” That’s true for a lot of things in life, but mostly true for electricity. People expect their lights to turn on and their devices to work, and only freak out when that doesn’t happen, but how exactly do we get the electricity needed to power the world?

Well, we have our natural resources, because aside from lightning, the power that we need isn’t found in the world. Humans have to generate it, and we do that with power plants. Power plants take natural resources, such as the sun, water, heat, and wind, as well as fossil fuels and transform it into electricity.

Most electricity works on the form of rotation, where wind spins a turbine or water runs in a water wheel, and that rotation is attached to a generator. The generator spins a magnet that rotates and is surrounded by wire, which creates an electrical current. Once the current is up and produced, the voltage is sent through directional couplers and then into the local power grid.

Then the power of the voltage is diluted and that weaker power is sent to buildings and homes to provide a steady electricity stream for all devices. The electricity is sent through conductors because it will always follow the path where it is less opposed, and that’s why it always goes towards the ground if it can.

Electricity is extremely fascinating when it comes to how it works and how a few power stations can provide power for entire city blocks. Since electricity and electric power are so important to us when it comes to our day to day lives, we have a duty to learn as much about it as we can.
