Constant current source

Dear all,
i want to design a constant current source of 100mA but with minimum voltage of 24v i have added the regulated 24v supply n series with constant current source .will this change the constant current ?
please help

Constant current source

You schematic looks confused, cause you draw an output voltage to the current source. To clarify, what you actually mean with

a constant current source of 100mA but with minimum voltage of 24v

you may want to draw a voltage/current characteristic curve. But whatever you intend, it seems unlikely, that the shown circuit is a solution.

Re: Constant current source

hi
if u want constant current source then use LM317T it works upto 34V DC.

from datasheet you can get the application notes of configuration for current source,
it is simple resistor alone what we require.

thx.
