Im planning to make a power supply circuit. my source is 24 v ,5 A battery.how can i regulate the current so as to supply to a 250 mA ,24 V to a 2.45 Mega Ohms load.?
 

Re: 250 mA 24 V power supply

You can't !

Use Ohms law, I = V/R, the most current you can draw from 24V into 2.45MΩ is
0.000009795A. That's way short of 0.25A !!
