I need help! WHEATSTONE!
http://en.wikipedia.org/wiki/Wheatstone_bridge
My pic. is almost same as this one, but R2 on the pic. is Rx at mine, Rx at the pic is R4 at mine. Pleas draw it up and help me:
VE(voltage at left) is 9 V.
VG(voltage in the middle) is 3V
R1=R3=R4=10 KOhm.
What is Rx?
I do not know how to solve it if VG is not zero.
