This is the relay circuit,which I using in my project.
Is this LED(LD2) connection in this circuit is correct or have to invert the LED.
By present circuit,is there any possible for flow of GND to relay coil point by placing the LED this this..?
 

Hi,

is there any possible for flow of GND to relay coil point
The only way to GND is via the BJT. The LED also get's it's GND via the BJT.
Thus it's not possible that the LED causes any GND current for the relay coil.

You may easily check this on your own by using a (colored) pen.
--> You wiil not find a path from VCC via relay_coil and LED to GND
