Problem 1: Consider the following Wheatstone bridge:
a) Solve R3
b) In the bridge circuit shown above, the bridge is nulled with R1 = 1000Ω, R4 = 421Ω, and R2 = 500Ω, Find the value of R3.
c) The resistor in the bridge shown above are given by R1 = R2 = R3 = 120Ω and R4 = 121 Ω.
If the supply voltage Vdc = 10.0 V, Find the voltage offset Vo.
