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

Greetings Ivano,

We request that you always start your own thread rather than tack your request for assistance onto an existing thread.
