Electrical power is the flow and existence of electrical charge. The flow of electrical charge is created by a generator and is used to transfer power from one location to another. With electricity, you can move energy from a distant location to a closer location, which allows you to accomplish more simple chores easily. An object that allows electrical charge to pass through it is known as a conductor. Wires and other metallic objects are good conductors, which allow electrical power to pass through them and transfer electrical energy from them to other places.
There are two types of electrical circuits: user-defined and static. User-defined simply gives instructions on how to wire or build a particular device. A user-defined circuit normally consists of at least one input device, such as a battery or generator, and at least one output device, such as a light bulb or radio. There are many different kinds of devices that can be added to a user-defined circuit. Many common household products, such as lights, clothes dryer, and oven can be plugged into a generator to produce electricity. Even vehicles, like boats and airplanes, can be wired together to create larger amounts of electricity.
A static electrical circuit is different in that there is no active input to generate electricity. Instead, the flow of electrical charge is created by the simple application of pressure onto any two conductors. The conductors are often coated with a substance that prevents the passage of electrons, thus creating a conductive path for the charge to flow through. If a current is applied, the coating permits the electrons to flow freely through the two conductors. When a person touches the two conductors and touches a nearby source of current, a temporary electrical circuit is created.
- Inductance is caused by the application of an electromagnetic force along a conducting piece of metal, which induces electric field lines into the area. Any conductive material will do, but there is a special type of metal called induction.
- The most common of these metals is copper, and the most common induction inductive coil is a wire wound around a mandrel or other shaped metal, such as a barrel.
- When a continuous current is applied, the induced magnetic field lines are forced between the copper wire and the induced induction coils, resulting in an electric circuit.
Circuit Uses:
A parallel circuit uses a portion of one circuit to control the output of another. In the example above, if the two copper wires are the output path for the magnetic induction coil, and the one wire controls the electrical current, then the two wires are considered parallel. Any given wire can be used as a parallel circuit component as long as the proper cabling structure is in place. Any current that flows from one parallel component to another must follow a specific path to ensure there is an even current distribution.
There are three different ways a magnet can create a parallel electrical path: a permanent magnet source, a magnetic field, or a component attached to the circuit that is turned by the magnetic field. A permanent magnet source is an extremely hazardous component because it is very powerful, and it also attracts every metal in its vicinity. Therefore, it can easily draw in and push back any electrical current that is flowing in an electrical circuit. A magnetic field on the other hand creates a non-permanent magnetic field, which allows it to repel any metal that is near it.
