#94858 - wheatstone bridge Responding to: ???'s previous message |
hi guys i found out that i probly could use a wheatstone bridge to measure the resistance but i found a formula to calculate the output of a wheatstone bridge but i need be able to calculate rx the unknown resistance so i was hoping someone might be able to show me how to transpose this formula
Vout = vin(r3/(r3+rx)-r2/(r1+r2) if some could show me how to rearrange this formula to find Rx i would really appreciate it thanks |
