7.- The Wheatstone Bridge. The circuit shown in the figure, called a Wheatstone bridge, is used to determine the value of an unknown resistor \(X\) by comparison with three resistors \(M, N\), and \(P\) whose resistances can be varied. For each setting, the resistance of each resistor is precisely known. With switches \(K_{1}\) and \(K_{2}\) closed, these resistors are varied until the current in the galvanometer \(G\) is zero; the bridge is then said to be balanced. (a) Show that...
