The Wheatstone bridge in the circuit shown in Fig. P4.72 is balanced when R3 equals 3000 Ω. If the galvanometer has a resistance of 50 Ω, how much current will the galvanometer detect, when the bridge is unbalanced by setting R3 to 3003 Ω. (Hint: Find the Thévenin equivalent with respect to the galvanometer terminals when R3 = 3003 Ω. Note that once we have found this Thévenin equivalent, if is easy to find the amount of unbalanced.
