# What Is Electricity?

## Electricity

Electric current is a flow of charged particles that move through an electrical conductor. It is the rate at which the flow of charge is measurable. Hence, electric currents are usually measured as the flow of electric charge across a surface or a controlled volume. The flow of electric charge can occur in many ways. For example, an electrical current can flow from an electricity meter to a circuit, or from one outlet to another.

## The movement of electrons in an electric current is called a flow.

The current consists of positively charged particles, known as cations. These particles are found in atoms with a positive charge. An electrical current flows in a direction where the lowest potential is found, which is negative. Therefore, when an object experiences a low potential, the electrons will discharge and move to the corresponding positively charged atoms.

## To measure electrical currents

you can use a multimeter, magnetometer, or photometer. However, it is more difficult to directly probe individual particles than to measure magnetic fields. Using a satellite, highly-tuned instruments are the most popular way to measure currents. It is possible to derive the currents’ characteristics through the application of Maxwell’s equations. If you’re looking to learn about electrical currents, you’ll need a textbook with a good understanding of electricity.

## Electrical currents can cause problems in the home.

If you plug a wire into an outlet and connect it to a battery, an external electric field will be created, which points downward. This force causes free electrons in the wire to move in opposite directions. Because of this force, they will begin to bounce around in the opposite direction of the electric field. This net-ordered movement is called a “runaway” process. And this process will continue until the source of voltage is completely depleted.

## The flow of electrical currents depends on a variety of conditions.

For a current to flow, there must be a difference in the potential between two points. This difference, called a voltage, is caused when an electron moves within a wire. An electric current is only possible when there is a voltage difference between two points. In other words, the charge in the wires is positive when the voltage is greater. The opposite is true if the resistance is higher.

## A wire connected to a battery will create an external electric field.

This electric field points down the length of the wire. The force will cause the free electrons inside the wire to speed up and move in the opposite direction. This net orderly movement is called an electric current. It is the force that allows electricity to flow in a circuit. It is the flow of electricity. The charge generated by an electrical current is also a form of energy.
