These three terminals are known and labeled as the Emitter (E), the Base (B) and the Collector (C) respectively. Common Collector Configuration — has Current Gain but no Voltage Gain. 4.7.1 NPN transistor configuration NPN transistor configuration The construction and terminal voltages for an NPN transistor are shown above. The above mentioned strategy will enable us to harvest solar energy in an effective way for the operation of the circuit and for powering the street light also.


Finally, the high collector current flowing through the relay, diode, LED and resistor makes the LED glow. Automatic Streetlight needs no manual operation of switching ON and OFF. The system itself detects whether there is need for light or not. Footprint acronyms A unique name is assigned to each footprint. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current and to extract modulation from radio signals in radio receivers.

This project exploits the working of a transistor in saturation region and cut-off region to switch ON and switch OFF the lights at appropriate time with the help of an electromagnetically operated switch. Relays are used where it is necessary to control a circuit by a low-power signal with complete electrical isolation between control and controlled circuits or where several circuits must be controlled by one signal. Случилось так, что мы с женой купили светильники, чтоб поставить на тумбочках возле кровати. И всем были хороши светильники, кроме одного — выключатель у них был только на шнуре, и чтоб выключить или включить его — приходилось бы лезть за тумбочку в поисках этого выключателя.
