1. is there any ic which can give me a constant level of voltage even two volts or in other words is ther any ic which give a regulated DC voltage of 2 or 1.7 volts volts for the varrying 1.23 to 1.5 volts.
2. i have already tried what u suggested but problem is the ouput is still varying and i require a constant 5volt dc level.is there any ic which can give me a constant level of voltage even two volts or in other words is ther any ic which give a regulated DC voltage of 2 or 1.7 volts volts for the varrying 1.23 to 1.5 volts
3. i am designing a circuit. the problem is i want to make the potential difernce between two points which hav some varrying voltage to some commmon constant level of voltage.can u guice me how. consider the case below: in my ciruit: the potential difference bw two supposed points a and b is in notnal stat:1.435volts the potential differnce bw the same points considered during excitation is about :1.28 volts to 1.60 volts now tel me how can i make the varrying difference corresponding to one constant level,that is whenever i got the varrying output during excitatoin above 1.430 volts i got some constant value like 5 volts. plz guide.
4. hi i want to use a realay, to conrtol a bulb of 60 or 100watt using microcontroller ouput. can anyone tel me which relay to be used keeping in view the controling parameter which wold be the dc ouput from microcontroller maximum of 5 volt and the bulb operating voltage which wold be220v ac. thanks for ur replies.
5. thanks to all of the contributers to my project. me got A++ grade in the project. but i wold strongly recomend that before doing anything just read the monostable operation of the 7555 ic. all the questions wold be solved bc how this circuit works and how the 7555 and the inciming signals works will be clear.
6. can u plz tel me what is the function of the capacitor c2 that is attached to the shorted pin 6 and 7 and then to ground.
7. me asking for the calculations of the indutor indectance and the capacitor attach to it
8. another problem. my teacher has asked me to give him the comlpete design.can anybody help me here now
