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...

An RTD forms one arm of a Wheatstone bridge, as shown in Figure below.
An RTD forms one arm of a Wheatstone bridge, as shown in Figure below. The RTD in a balanced is used to measure a constant temperature, with the bridge operated mode. The RTD has a resistance of 25 V at a temperature of 0°C, and a thermal coefficient of resistance, α= 0.003925°C, The value of the variable resistance R1 must be set to 37 V to balance the bridge circuit.
