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...

In the circuit shown below the ammeter consists of a
galvanometer, with resistance Rg = 100 Ω, in parallel with a
‘shunt’ resistor, Rs = 2.00 Ω. The current, Ig, flowing through the
galvanometer is 22.1 mA. The external circuit resistance is Rc =
20.0 Ω. If the EMF of the cell is 25.0 V, what is its internal
resistance?

Consider the circuit shown below which is used to monitor the force applied to a strain gauge. The circuit is called a "Wheatstone Bridge". The current-measuring device is called a "Galvanometer", and it has an internal resistance of \(50 \Omega\). Resistor \(R_{3}\) represents a force-sensitive resistor (strain gauge) whose resistance increases with bending moment.For the resistor values shown, the circuit is balanced and no current will flow through the Galvanometer. What will be the magnitude and direction of the current...
