Homework Statement
The circuit in the figure is composed of two batteries (E1 = 6 V and E2 = 4 V) and three resistors (R1 = 4 , R2 = 4 , R3 = 5 ) as shown.
(a) What is the current I3 flowing through the batteries?
I3 = .286A (no problem here)
(b) What is the voltage Vb - Va between the points a and b in the circuit?
Vb - Va = V
So i combined the parallel Rs to get R1 + R2 = 2ohms
So voltage in is 2V right?
Then voltage on other side of Req should be .579V right? (because I=.286A)
so then 2V - .579V = 1.43 = wrong answer
please help!
thanks
