1. The problem statement, all variables and given/known data Three resistors and two batteries are connected as shown in the figure. The magnitude and direction of the currents in the unknown resistor "R" at the right and the 6.0 ohm resistor on the left are shown in the figure. The current in the 4.0 ohm resistance flows from B to C. The emf of the batter on the left is unknown and is labeled. For parts (a) through (d) fill in the blanks and for part (e) circle the correct choice. I drew a picture of the diagram, hopefully you guys can see it and understand: http://img683.imageshack.us/i/imgie.jpg/ a) The current flow in the 4.0 ohm resistor is? I put the answer is 11amps because Kirchoff's rules for a joint. b) The unknown resistance R is? I know that resistance is equal to V/I, but I have tried to answer this question and it does not match up with the given answer. C) The unknown emf is? I am not even sure where to begin with this one. d) The absolute value of the voltage difference between A and B is? I put 50V because 1Ax6ohms + 11Ax4ohms = 50 Volts Any insight would be helpful. Thanks!
