Homework Statement
Determine the magnitudes of the currents through each resistor in the above circuit. The batteries have emfs of E1 = 9.2 V and E2 = 13.8 V, and the resistors have values of R1 = 11.8Ω, R2 = 29.3Ω, and R3 = 34.3Ω. Use positive numbers for currents to the right, and negative for currents to the left.
Homework Equations
Kirchhoff's Laws (junction rule and loop rule)
V=I
The Attempt at a Solution
I found three equations to figure out one of the currents.
Loop 1 --> 9.2-29.3(I2)-11.8 (I1)=0
Loop 2 --> 29.3(I2)-13.8+34.3=0
Junction Rule --> (I1)+(I2)=(I3)
I chose to solve for I2 first and I got 23/59.6 A
for I1 I got -2.1070 A
for I I got 2.4929 A
Neither of those are correct and I am not sure where I went wrong.
