# The Flow Of Electricity Through A Circuit

If you have ever had the pleasure of working in a Radio Frequency Tester (RF-T) or an RFID reader, then you know how fun it is. These devices send out radio waves that are recorded by an RFID reader. The reader will then convert the data into a meaningful number. You probably already know that, if you have ever bought something on credit, then the item was most likely purchased with a credit card. This is because credit cards are a method for people to guarantee themselves that they will be able to make purchases on a regular basis without overspending.

## Moving Electrons

Electric current is the movement of electric current through any conductive substance. Most commonly, electronics refer to utilizing changing magnetic electrical properties to transmit information from one location to another. Some examples of conductive materials include; copper wires, air, and even plastic. Electrical sensors convert any other form of non-conductive energy (electricity, light, heat, etc.) to electrical current so that an RFID reader can read what is happening mechanically.

When power is applied to a device, it changes the voltage across it in either a direct current or alternating current pattern. When using an RF-T or an RFID reader, the information needed to determine the direction of the electrical current is obtained by measuring the change in resistance across the wire. This resistance is measured in Ohms. Resistance is typically in exponential geometric forms, so a one-Ohm value means one volt will rapidly increase as time progresses.

The amount of energy flowing through any particular wire will also be known as their Inductance. The higher the inductance, the greater the amount of electricity flowing through the wire. An electric current flowing through a conductor will be in a smaller region than an electric current flowing through an insulator, which means that the energy is in a larger region. It is important to understand the difference between energy in energy. An electric current is a kinetic energy, while an electric field is electrostatic energy.

## How Generators Work

In addition to resistance to electricity, there are other factors that affect the flow of electricity through a circuit. Electromagnetic fields that are present will cause currents that are perpendicular to the flow. In this case, the flow of the energy is random. The opposite is true for a conducting metal, like copper. Copper will create a directional current when it comes in contact with a metal conductor.

As described earlier, the amount of current flowing through any given circuit is always in a state of exponential growth. The amount of energy that flows through a circuit is linearly proportional to the square of the voltage. As voltage increases, the energy content of each molecule increases as well, causing a greater molecular weight. This means that a higher volt will result in a greater molecular weight, which will result in a higher voltage. With this understanding, you can understand why some power supplies convert AC voltage to an alternating current (ACV).
