This is automatic light circuit when be become dark. It by use LED Lamp, be a place gives the light and this circuit has small-sized use volt supply 3V only.
The work of the circuit be when there is the light affects LDR1 will valuable the resistance at LDR1. It be down make Q1 work be born volt at fall straddle a pin C of Q1 compare with Ground be valuable a little more voltage bias to make Q2 work. By have D1 serial with a pin B of Q2 make volt at pin C of Q1 compare with ground must use volt about 1.4V arrive at make Q2 work. But when LDR1 no the light will make to is valuable the resistance more and more until make to have no current flow get along well with B of Q1 make Q1 do not work. Then have current flow through R1,D1 get along well with pin B of Q2 work cause LED1 stick bright. The part , VR1 , parallel connection with , LDR1 , as a result , for take keep fine the rapidity in taking light of LDR1

What are advantages and disadvantages of street lights?
Street lights help pedestrians to walk safely after sunset. The car drivers find it convenient to drive smoothly,as driving in a highway without street light is a nightmare. Well, the hellogene lights emits particles that are injurious to eyesight and human skin. On the humourous note, street lights cause inconvenience to those who commit highway robbery and darkness is the precondition to their professional job !
Will a circuit work if the resistance of the fixed resistor is larger than the resistance value of the thermistor?
In order to answer that, one would need to know what the circuit is designed to do (so that he would know how to tell when the circuit is "working"), and would also need to see the schematic diagram, in order to know exactly how the fixed resistor and the thermistor are configured in the circuit, and what other components are involved. Consider . . . If I came up to you on the street, or even for that matter in an Engineering lab, and I said to you "I've got a circuit with a coil and a resistor in it. Will it work if the impedance of the coil is greater than the resistance of the resistor ?", you would most certainly find yourself at a loss, just as I do when I read your question.

Explain the working of LDR and mention any five applications of LDR in detail?
A photoresistor, light dependent resistor (LDR) or cadmium sulfide (CdS) cell is a resistor whose resistancedecreases with increasing incident light intensity. It can also be referred to as a photoconductor.Applications:camera light meters, street lights, clock radios, alarms, and outdoor clocks
Are street lights on a series circuit or a parallel circuit?
Parallel. One light burning out does not stop all current flow to the other lights.

Who created the street lights?
Street lights date back thousands of years. As early as the 4th century Antioch had street lights. Street lights were also used in the 9-10 centuries by the Arab Empire. In 1417 in London Henry Bastien ordered lanterns to be hung on winter nights and by 1792 William Murdoch had installed gas lights in London. In the United States Ben Franklin helped with street lights and by 1816 Baltimore was the first city to have street lights.
