Homework Statement
In the circuit the battery is ##10V## and each resistor is ##4\Omega## find the voltage on AB
Homework Equations
1.KVL and KCL
2. ##V=IR##
The Attempt at a Solution
- ##I_{1}=I_{2}+I_{3}##
- ##10-4I_{1}-4I_{1}-4I_{2}-4I_{1}=0\rightarrow 10-12I_{1}-4I_{2}=0##
- ##10-4I_{1}-4I_{1}-3*4I_{3}-4I_{1}=0\rightarrow 10-12I_{1}-12I_{3}=0##
##I_{1}=0.66## ##I_{2}=0.5## ##I_{3}=0.16##
Because the voltage at B is ##0## all that is left is to find the voltage on ##A## which is ##10-8*0.66-4*0.16=4.08V##
Is it right?
