Homework Statement
A DC circuit which includes Emfx of unkown magnitude and orientation, at the location indicated is shown below. Note the 'ground' (V=0) in the circuit.
The potential between 'b' and 'a', Vb-Va, is measured to be 2.00 V.
a) The magnitude of Emfx is:
b) Calculate the current through the 8Ω resistor located on the far right. Use + sign for current flowing toward top of page.
Homework Equations
Kirchoff's Current law (Sum Iin=Iout)
Kirchoff's Voltage law (Sum V=0)
The Attempt at a Solution
First, to simplify this circuit, I added up all the resistors which were in series, so instead of having 6 resistors, I now have 3.
So my R1=5ohms, R2= 15Ohm, and R3= 11Ohm.
for a, I tried solving for the E magnitude by doing V(gE)= VE-Vg (Where g Vg is ground voltage which equals to 0). I don't know how the Kirchoff's law could help me with this.
I don't know where to go from here, I am absolutely confused because my teacher does not want to give me a little push either :(.
as for b, I guess i could get it once i get the answer to a.
