Basic Electricity

Basic Electricity. Basic electricity is described in many ways. When an electric circuit flows through a conductor, a magnetic field (or "flux") develops around the conductor. The highest flux density occurs when the conductor is formed into a coil having many turns. In electronics and electrical technology, a coil is usually known as an inductor.

Electrical Current Explained

The Charger will then convert this to give an output of around 19.5 volts and 3.33 amps of DC or direct current, which is represented by this symbol. AC and DC are different types of electricity, the plugs in your homes provide AC or alternating current. In this type the electrons do not flow in a continuous loop.

Electric potential (article) | Khan Academy

Electric potential energy is the energy that is needed to move a charge against an electric field. You need more energy to move a charge further in the electric field, but also more energy to move it through a stronger electric field. Imagine that you have a huge negatively charged plate, with a little positively charged particle stuck to it ...

Electricity explained How electricity is generated

Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.

Electrical energy

Electrical energy is energy related to forces on electrically charged particles and the movement of those particles (often electrons in wires, but not always). This energy is supplied by the combination of current and electric potential (often referred to as voltage because electric potential is measured in volts) that is delivered by a circuit (e.g., provided by an electric power utility). Motion (current) is not required; for example, if there is a voltage difference in combination with charge…
