Question

Constants Part A The Wheatstone bridge in the circuit is balanced when If the galvanometer has a resistance of 70 Ω, how much current will the galvanometer detect, when the bridge is unbalanced by setting R3 to 501 2? Take v 10 V. (Hint: Find the Thévenin equivalent with respect to the galvanometer terminals when R3 501 Ω. Note that once we have found this Thévenin equivalent, it is easy to find the amount of unbalanced current in the galvanometer branch for different galvanometer movements.) equals 500 Ω.
