(i) In a meter bridge , the balance point is found to be at `30 cm` from the end A when resistance `R` in left gap of bridge is of `12 Omega`. Find resistance `S` in the right gap of bridge (ii) If the cell and the galvanometer are interchanged in the balance point, would it effect flow of current through the galvanometer (iii) Calculate the balance point of the bridge if `R` and `S` are interchanged
Text Solution
Verified by Experts
There will be no deflection in the galvanometer as the condition of balanced bridge will still hold good.
