1. The problem statement, all variables and given/known data A combination circuit powered by a 6.0 V battery is shown. What is the total current through this circuit? I don't know how to determine where the signs go, for example if the right side of a resistor is positive or the left side is positive 2. Relevant equations What is the total or equivalent resistance of this circuit. 3. The attempt at a solution I found the total resistance and I tried to find the currents using Kirchhoff's law I1=I2+I3. For the first loop, I found the equation: -6+220*I1+2100*I2=0 For the second loop, I found: 4500*I3-2100*I2 Here is my work: -6 + 220(I2 + I3) + 2100*I2 -6 + 220*I2 + 220*I3+2100*I2 220*I3=-2320*I2+6 I3=-10.54*I2+0.027 This answer to I3 was plugged into the second loop equation: 4300*(-10.54*I2+0.027) 0=47430*I2 + 122.7 122.7/47430=I2=2.6*10^-3 A or 0.00259 I highly doubt that 2.6*10^-3A is the current for I2 but I don't know what I did wrong. I think it has to do with the fact that I don't know where each sign goes where (+/-). Any advice is appreciated!
