in the RC circuits in order to calculate time constant the resistance we are to take is the resistance of the branch in which capacitor is there or the net resistance of the circuit or something else? Also please reply the previous questions

It is a good question. In all problems that you might be facing R C as series components excited by DC source. You know what to do then. Interestingly if they are in parallel ( i am saying just r and c in parallel) it will still be ... well you might have the answer all ready. But what will happen if there is a case where a series RC has a parallel r ..then the idea is to find the equivalent impedance and the time constant will be c*(whatever you get) In this case R+r.

hope it helps

Short the battery , then find effective resistance assuming Capacitor as baettery , there you have R. C is already with you . So , it should be done . Hope it helps
