Is the Wheatstone bridge good for all resistor sizes? Why or why not?
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...
Why is a galvanometer used in a Wheatstone bridge? What purpose does it serve? Please explain.

Quarter Bridge configuration on Wheatstone Bridge has only one sensor. If with its configuration voltage is given 100 Volt, R1 = 80 Ω R2 = 80 Ω R3 = 480 Ω With R1 and R3 are on the upper part of Wheatstone Bridge, R2 and R4 are on the lower part of Wheatstone Bridge, determine: a) Schematic of Wheatstone Bridge, strain gauge sensor, and Op-Amp for measuring a strain b) R4 so the voltage of Wheatstone is balanced c) Using...
The resistance of an RTD is measured with a Wheatstone bridge circuit. To eliminate errors from wiring resistance inaccuracy, RTDs use matched lead wires in a 3-wire or 4-wire bridge circuit. 1. Draw a simple 2wire Wheastonc bridge cret 2. Draw a simple 3-wire Wheatstone bridge circuit. 3. Draw a simpie 4-wire Wheatstone bridge circuit. 4. Explain the advantage of using a 3-wire or 4-wire Wheatstone bridge circuit instead of a 2-wire circuit.
