Junction

Irumbuliyur Junction is one of the important junctions in the city of Chennai, India. It is located at Irumbuliyur near Tambaram in Chennai at the intersection of NH 45 with the Chennai Bypass.

The Educational institution such as Nursing & schools functioning in Irumbuliyur since 1993 and 1987 under the name of Anbarasu School of Nursing and Tagore Matriculation School to cater the educational need of local public.The highway and the railway line divide the town into East Tambaram and West Tambaram. The neighbourhood is served by the Tambaram railway station of the Chennai Suburban Railway Network.The main road through West Tambaram connects the districts of Lakshmi Nagar, Krishna Nagar, Bharathi Nagar, Old Perungalathur, Madhana Puram and Mudichur, ending at the Vandaloor - Oragadam road. West Tambaram has been growing rapidly since the development of the Vandaloor-Nemilichery Outer Ring Road.

Supermarkets in West Tambaram include Heritage, Reliance Fresh and Nilgiris are in West Tambaram. Banks include SBI, Canara Bank, Axis Bank, ICICI Bank, Indian Overseas Bank, and Indian BankA three tier interchange has been built to ease the flow of traffic between Chennai bypass and NH 45. It has 3 levels

Level "-1" for traffic from Tambaram to Maduravoyal.
Level "0" for traffic from Chengalpattu to Tambaram and Maduravoyal, from Tambaram to Chengalpattu and from Maduravoyal to Tambaram.
Level "+1" for traffic from Maduravoyal to Chengalpattu.

An electrical junction may be either a thermoelectricity junction, a metal–semiconductor junction or a p–n junction (p-type semiconductor–n-type semiconductor junction). Junctions are either rectifying or non-rectifying. Non-rectifying junctions are called ohmic contacts. Electronic components employing rectifying junctions include p–n diodes, Schottky diodes and bipolar junction transistors. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.

This effect can be used to generate electricity, measure temperature or change the temperature of objects. Because the direction of heating and cooling is determined by the polarity of the applied voltage, thermoelectric devices can be used as temperature controllers.

The term "thermoelectric effect" encompasses three separately identified effects: the Seebeck effect, Peltier effect, and Thomson effect. The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may refer to this process as the Peltier–Seebeck effect (the separation derives from the independent discoveries of French physicist Jean Charles Athanase Peltier and Baltic German physicist Thomas Johann Seebeck). The Thomson effect is an extension of the Peltier–Seebeck model and is credited to Lord Kelvin.

Joule heating, the heat that is generated whenever a current is passed through a resistive material, is related, though it is not generally termed as thermoelectric effect. The Peltier–Seebeck and Thomson effects are thermodynamically reversible,[1] whereas Joule heating is not.
