Ma'am as the circuit I have studied that connect +ve terminal of battery with HRB and then HRB to +ve side of Galvanometer and from same +ve side of galvanometer LRB is connected and then we have to connect -ve side of galvanometer to key 1 and key 2 and connect key 1 with -ve side of battery so ma'am is this connection is right?? Please reply soon ma'am

[@pvtSana]

Yes this is also correct. We just have to connect in parallel way !! Both are correct as in both cases there will be deflection shown in galvanometer.

Why we close one key while measuring theta and close both key while measuring half deflection?

When we close one key, other circuit is disconnected. When we close both keys, both the branches are connected.

Mam one doubt... Should we change the value of shunt resistance or should it stay constant?

[@physicswithaliva9791]

To get the half deflection we are adjusting the shunt resistance. So the value of shunt resistance is not taken by choice.
