(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

determine the terminal voltage in each battery.

Emf_{1}=18V

r_{1}=1 ohm

EMF_{2}=12V

r_{2}=2 ohm

R=6.6 ohms

also the batterys currents are opposing each other.

2. Relevant equationsVab=emf-Ir

3. The attempt at a solutioni used kirchnoffs rule to find the current I , 18-I6.6-12-I2-I=0 and got I= .625 then i thought i would just use Vab=emf-Ir to find the terminal voltage of each battery however im not getting the correct answer... could someone please explain this to me i have a test tomorrow morning and i really need to figure this out! the answers i got were 17.375 for the 18V batt and 10.75 for the 12V batt
