Car Electrical systems construction. The electrical system of a car operates on a small fraction of the power of a household circuit with power source the battery. Car electrical system consists of two main charging starting and ignition circuits. The ignition circuit furnishes the high-tension impulses to the sparkplugs. Modern cars have a 12 volt battery with own capacity measure. Battery capacity is measured in amp/hours.
Power lights, electric motors, the sensors and gauges of electrical instruments, heating elements, magnetically operated locks, the car radio are power of ancillary electrical circuits.
A Car Generator – is a dynamo. It is able to produce electricity through the rotation of tightly wound fine wires in a magnetic field. This magnetic field is maintained by a fixed arrangement of magnets or electromagnets surrounding the spinning windings of wire. The current and voltage produced depends on the speed at which the wires spin and the strength of the magnetic field.
