100. (a) From symmetry we see that the current through the top set of batteries ( i ) is the same as the current through the second set. This implies that the current through the R = 4.0 resistor at the bottom is i R = 2 i . Thus, with r denoting the internal resistance of each battery (equal to 4.0 ) and ε denoting the 20 V emf, we consider one loop equation (the
