HI...

i'm not being able to understand where does this formula come from:

legend

Vo= OUTPUT or revelation voltage of the bridge

E = supply voltage

x= unknow resistance

a, b, c = left resistors (a next to b ; c next to x )......

...it should come from the voltage divider but cannot see how...

Vo= (Ex/x+c)-(Ea/a+b) = [(x/x+c)-(a/a+b)]E

..hope someone is gonna help me

please
