Find the potential of point a with respect to point b in the figure (Fighttps://s.yimg.com/hd/answers/i/1ffe0f8aeaf145679cde38f7812b1c7f_A.png?a=answers&mr=0&x=1413484693&s=0943630e47eb74ae023909f7d39f74e3 [Broken] ure 1) . If points a and b are connected by a wire with negligible resistance, find the magnitude of the current in the 10.0V battery. V=IR, Req=R1+R2, 1/Re = 1/R1+1/R2 So basically added up the resistors in series on the side getting 4 ohm and 3 ohm respectively. Im stuck because the a-b is disconnected which is something i haven't seen until this problem. also i cant seem to simplify the circuit into a single "line" if you know what i mean.
