Question
The correct equation for this Wheatstone bridge isa.Rx= R3 (R2 / R1)b.None of thesec.Rx=V R3 (R1 / R2)d.Rx= R3 (R1 / R2)e.Rx=V R3 (R2 / R1)
Solution
The correct equation for a Wheatstone bridge is:
d. Rx= R3 (R1 / R2)
This equation is derived from the principle of a Wheatstone bridge, where the ratio of the two resistances in the first pair is equal to the ratio of the two resistances in the second pair. In this case, Rx is the unknown resistance we're trying to find, R1 and R2 are known resistances, and R3 is a variable resistance adjusted until the bridge is balanced.
