i have one silly doubt , anyone will help me ,
Case 1:
If we a connect a Ammeter in series with the resistor such that +ve of Ammeter is connected to +ve of the supply and its -ve to the first resistive lead &&
Case 2:
Whereas we connect +ve of Ammeter to the second resistive lead and the -ve of Ammeter to the -ve of the supply will the current recorded by the Ammeter will be the same.
(Conditions: Supply is DC and Only 1 Loop is there, everything hence is in series)

 

if u follow ur way u ll get d same result bt in negative

the correct and accurate using of ammeter is you have to open d circuit at point which u want to measure it
lets say ur point is + lead of resistor then connect +v of ammeter to d +lead of resistor and -v of ammeter to other point to close d circuit the switch on the supply. now u can read the current follows the point wht u mention.

 

if u follow ur way u ll get d same result bt in negative

No the results will be the same and both negative.

It is because the current will flow through the ammeter in the same way.
