Homework Statement


I was trying to apply the formula of bridge


Homework Equations


[tex]V_{o} = (\frac{1}{1+R4/R2})-(\frac{1}{1+R3/R1})[/tex]


The Attempt at a Solution


File is attached....Small numbers with resistor names are their values in ohms...
the answer I get is 6v....Here it is 1.5 v....

The equation should be:
[tex]V_{o} = [(\frac{1}{1+R4/R3})-(\frac{1}{1+R2/R1})]V_s[/tex]
With[tex]V_s = 3V[/tex] you could never have [tex]V_o = 6V[/tex] with a totally passive circuit.
