| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law

Temperature Display Circuit using LCD ( Liquid Crystal Display ). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors ) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree then the output of sensor will be 350mv or 0.35V For working with LCD it is necessary to have Microprocessor. We have used Arduino Controller Board which is AN OPEN-SOURCE ELECTRONICS PROTOTYPING

ELECTRONIC COMMUNICATIONS SYSTEMS Wayne Tomasi‚ 5th edition Introduction to Electronic Communications Electricity began in 1837 when Samuel Finley Breese Morse invented the first workable telegraph. In 1894‚ Marchese Guglielmo Marconi successfully transmitted the first wireless radio signals through Earth’s atmosphere. In 1906‚ Lee DeForest invented the triode vacuum tube. Commercial radio broadcasting began in 1920 when radio station KDKA began broadcasting amplitude-modulated

gruesome squeals and sounds of pain coming from somewhere near my room. Very frightened‚ almost thinking there was a murderer outside‚ I had the courage to take a peek out the curtains of my windows... Horrified and shocked‚ even life scarred‚ I witnessed the murder of not a human being‚ but of a horse...my horse. I couldn’t bear to hear that deafening sound of my horse‚ Jaden‚ crying in pain. I didn’t know what to do. There were only two thoughts in my head. I could quickly but quietly sneak into my

Although some may disagree about athletes getting paid more than 10 million dollars they do hard work for that money. I think that they should not be paid almost 10 million dollars because that type of money can go to homeless people and kids they can go to kids to get their diploma to go to college and get a good job. Ten million dollars could go to buildings that are needed. In my opinion is i think it should go homeless people more than anything cause they could have been through a lot. For example
