Homework Statement
when the balance point is achieved , there're no current passing thru , so Galvanometer should show 0 . Am i right... so there's no current passing thru the 20 ohm resistor . so my working is ( 8.1/120 )(40) = 2.7 V ...
correct me if I'm wrong...
Homework Equations
The Attempt at a Solution
V_xy = V_ac = (9/10) x 10 = 8.1v
k = 8.1/120
V_xy = k (40) = 2.7v
(5/ (5+20+2) ) X E " = 2.7 V
E" = 14.58v[/B]
