Hi satish,
The resistor which is connected in series between the emitter of series pass transistor and the output terminal it will be a very low ohm resistor HI wattage. If your ps is imec make it willbe .1 ohms.

Sorry, I don't understand your circuit diagrams. It looks like there are parts missing and connections not shown.
Anyway, there's a 2n3055 transistor in the second circuit. That may be the output transistor. If so, you could look for a low value resistor connected to it, or near it. The value is probably something like one Ohm or lower
That resistor probably have small resistance for measuring current as shunt. Because small resistance lets say 0,1R your ohmeter says that is very small resistance or shorted. :wink:
when i switch on the power supply voltage varies exactly what we want but the current is initially loading to 0.9A without connecting any load and a i can also vary(up-to 0A) the current but this should not vary.
Hi satish,
problem is not solved i know. You did not measure as i told in post no#16, I am thinking it is a metering problem first let us make it clear
