Electricity

**Electricity** is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.

## Overview

The presence of charge gives rise to an electrostatic force: charges exert a force on each other, an effect that was known, though not understood, in antiquity. The force acts on the charged particles themselves, hence charge has a tendency to spread itself as evenly as possible over a conducting surface. The magnitude of the electromagnetic force, whether attractive or repulsive, is given by Coulomb's law, which relates the force to the product of the charges and has an inverse-square relation to the distance between them. The charge on electrons and protons is opposite in sign, hence an amount of charge may be expressed as being either negative or positive. By convention, the charge carried by electrons is deemed negative, and that by protons positive.

The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.

## Electricity in the New World

### Third Civilization Area and Outside the Civilization Areas

Before the arrival of Japan, the inhabitants of this region only knew electricity in its natural form, which was lightning or static electricity. Those who possessed the ability to control magic were able to conjure up lightning and use it as an offensive spell. However, no one was able to harness electricity for civilian usage. That all changed after Japan began relationships with nations such as the Qua-Toyne Principality and the Quila Kingdom. Once they began improving their infrastructure and installing utilities and electrical grids, the people began to experience a huge boost in the quality of life, as they were able to use the power of electricity in all domestic affairs such as night-lighting, home appliances, transportation and communication. Soon afterwards, other nations would follow their lead.

### Second Civilization Area and the Gra Valkas Empire

Both Mu and the Gra Valkas Empire are mechanized nations and therefore have been able to harness the power of electricity. For Mu, they have only seen electricity as a power source and not as a means to transmit information. Therefore, they have yet to learn the application of electricity in the form of electronics and computers.

For the Gra Valkas Empire, they have taken the next step towards electrical usage with their vacuum tube technology. As a result, they are able to construct primitive computational devices. However, these computers are primitive, bulky and are prone to breakdowns and overheating.

### First Civilization Area

As always, the Holy Milishial Empire represent a kind of forward and backward thinking. Since they are dependent on magic, they are able to summon up electricity as lightning. However, they also seem to know that electricity can be used as a power source. Some of their devices are electrically powered.

### Japan

As the leading nation with the highest technology, Japan has the expertise in both generating and using electricity. Their usage of electronics are among the very best and their computational power is without peer.
