In a turn indicator, the measurement of rate of turn consists

Resistance: Opposition to offer the components of a circuit when current flow is the ohm eléctrica.Medida. The fixed resistors: The electrical resistance is the difficulty posed by the materials to the passage of electrical current. In electronic circuits we use these components to limit or regulate the amount of current flowing through a given circuit, so as to protect some components that should not circulate a high current intensity. Resistances variables (potential): The potentiometers vary their resistance between zero ohms (Ù) and a maximum value which is indicated on the component. To vary the resistance value is necessary to turn a shaft or move a cursor. Example: the volume control of a radio or the remote control speed of a car teleridigido. Resistances variables (temp)These resistors change their value according to the temperature at which they are subject. There are two types: NTC: their resistance decreases with increasing temperaturaPTC They increase their resistance with increasing temperature. Variable resistors (light) The resistance decreases with increasing its value tremendously the amount of light they receive from thousands of ohms to only a tens (Ohm's Law). If the resistance decreases, the intensity increases. TipoP Diodes: The default is electron doping. It lacks electrons, thereby creating voids that allow electrons to move easily Type N: The dopant provides electrons that help improve electrical conduction.


LED Operation is the same as that of the diodes, ie becomes a conductor when it is directly polarized, but has the peculiarity that illuminates when the current leads.Capacitors that store electrical elements and use it when needed. They consist of two opposing metal plates that are separated by an insulating material (dielectric). Each plate is joined by a terminal for connection to the circuit. Importantly, electrolytic capacitors have polarity. FIXED: fixed capacity set by the manufacturer and its value can not be changed. Its characteristics depend mainly on the type of dielectric used variables: capacity can be altered intentionally by mechanical or electronic. Transistors electronic component most important and most used. This consists of three layers of semiconductor material in which we placed three terminals and then encapsulate that can be mounted on a circuit. According to the semiconductor layers we use, we can obtain two different types of transistors. The terminals are called transistor collector, base and emitterOperation To operate a transistor as a switch open or closed 3en necessary to circulate or not current flowing between the collector and emitter. In both cases, two resistors inserted
