Alright, I think I got it. I set V1 = ε1 - ir1 = 0 and got ε1 = ir1 and also ε2 = ir2 Subbing 'i' into the equation I had simplified to above produces, for emf #1, I get R to equal .004Ω (which is what the back of the book says). Doing the same for emf #2, I get -.004Ω. My only...

Homework Statement ε[1]=12v internal resistance[1]=.016Ω ε[2]=12v internal resistance[2]=.012Ω some unknown resistance 'R' in a stand alone resistor. a) what value of 'R' will make the terminal-to-terminal potential difference of one of the batteries zero? b) which battery would it be...
