How Electrical Circuits Work

If you can make sense of voltage current and resistance then you can make sense of how electric circuits work.

How electrical circuits work. The blood vessels carry the flow of blood through your body. Also shown is a schematic representation of the circuit showing the driving voltage current flow and resistance to the flow of electricity offered by the heater. Electricity comes from electrons motion. Your blood vessels arteries veins and capillaries are like the wires in a circuit.

The main panel is usually right next to or under the meter. An electric circuit is in many ways similar to your circulatory system. Among the most important are that the voltage in your house is higher the power source never runs down and the current isn t direct dc as it is with a battery but alternating ac. A simple electrical circuit consists of a power source two conducting wires one end of each being attached to each terminal of the cell and a small lamp to which the free ends of the wires leading from the cell are attached.

Electron are part of atoms. An electric meter monitored by your electric utility company is mounted where the electricity enters your house. This is the central distribution point for the electrical circuits that run to lights receptacles and appliances throughout the house. The wires in a circuit carry the electric current to various parts of an electrical or electronic system.

The electrical circuits in your home operate by the same principle with a few key differences. An introduction to a simple electrical circuit. Well they work approximately as water flow works. A circuit is a complete path around which electricity can flow.

The battery pushes the electricity along the wires from the positive terminal through the bulb and back to the negative terminal. Copper and aluminum are the most common conductors. Materials that allow electric current to pass through them easily called conductors can be used to link the positive and negative ends of a battery creating a circuit. They are these tiny black things gravitating around the core of the atoms which is made from neutrons and protons.

Electric circuits are composed of wires and other components like light bulbs transistors computer chips and motors. An electric circuit is an unbroken path along which an electric current exists and or is able to flow. The illustration below shows a heater connected to a socket outlet.
