# PHOTOCONDUCTIVE CELL PHYSICS PROJECT

12th class is a no risk class. It is the class which decide your future. Whether you are going to work in MNC or going to work with usual private firms, it all depends here. To ensure the good marks to students we always stands behind them with all practical and theoretical support on Physics investigatory project. These Physics investigatory projects are usually have to be made by all students with physics and to be shown in boards practical. We at Gurukul Technicals Institute provide every student the theory behind the projects and give all possible required material to make the project work successfully. We duly provide equipped lab with latest lab materials. Conductors and Semiconductors are provided with Circuit diagram so that student can make project easily. Students make projects such as Full wave rectifier, Half wave rectifier, Fire alarm, rain alarm, Electromagnetic Induction, Logic gates(AND gate, OR gate, NOT gate, XAND gate, XNOR gate), Transistor as switch, Transistor as amplifier, Charging and Discharging of Capacitors, Series and Parallel Resistance etc etc. Students also get help on making these above given projects to made on cardboard or on breadboard as instructed by teacher. Students are also welcome to take help on report on given physics investigatory projects. After reading this website you can also send this information to your friend or relative studying in 12th class so it will make useful to him/her.
