how to convert 10V dc to 5V dc , besides using voltage divider and zener diode ..??

 

op amp

same setup you would use to turn 10V into a +5 and -5 volt supply.

 

cn u plz explain me dat as well or if you could give ne link where i would find d above..??

 

If you are speaking of a power source, a 7805 voltage regulator might be superior.

Can you say what to application is?

Linear regulators like 7805 are simple but efficiency less.

Swithcing regulator - like ti3524 can come handy. Pls visit to understand buck regulator

7805 is the best approach if load max's at 1 Amps.

As long as you have a large heatsink. Dropping 10V to 5V @ 1A is 5W its got to dissipate.

 

thnx all..
