How Electrical Circuits Work

Take the simple case of an electric light.

How electrical circuits work. Reason we have electrical circuits is to do some useful work for us. An electric circuit is an unbroken path along which an electric current exists and or is able to flow. In a lamp this is to provide light in a heater to give us heat and in an electrical car to drive us around. An introduction to a simple electrical circuit.

The equation for electrical work is equivalent to that of mechanical work. The basic components of analog circuits are wires resistors capacitors inductors diodes and transistors analog circuits are very commonly represented in schematic diagrams in which wires are shown as lines and each component has a unique symbol analog circuit analysis employs kirchhoff s circuit laws. The blood circulating through the body supplies various organs like your muscles brain and digestive system a battery or generator produces voltage the force that drives current through the circuit. How electrical circuits work.

Electric circuits move power from the power station to the connected equipment so that we can get this useful work out of them. A simple explanation on how an electrical circuit operates. It provides the force or pressure for blood to circulate. Your heart is the pump that drives the blood circulation in the body.

Where q is the charge of the particle q the unit charge e is the electric field which at a location is the force at that location divided by a unit test charge f e is the coulomb electric force. A simple electrical circuit consists of a power source two conducting wires one end of each being attached to each terminal of the cell.
