What is electricity, and how is it made?
In: 0
Electricity is energy that is transmitted as an impulse by electrons displacing each other between atoms in matter. Electrons respond to magnetic fields (magnetic fields displace electrons, displaced electrons also create magnetic fields). To create electricity, you pass a wire through a magnetic field. This changes the electrical potential along the wire. If the wire forms part of an electrically circuitous path, then current will flow.
Electrical energy can also be produced chemically. Some chemical reactions yield a surplus of electrons in one kind of metal and a deficit in another metal. These surplus electrons will readily displace those in a nearby conductor. Like in the magnet wire analogy above, if the conductor forms an electrically circuitous path between the two metals, then current will flow.
