A circuit comprised of 3 batteries 4.0 0 A 4.5 0 and 5 resistors is connected as shown. The directions of the 4.80 52 V three currents marked in the diagram are not certain; 44 V they can point the other way 28 V 1.5 0 (report as negative if they do). 4.0 0 B a) Use the junction rule to relate the three marked currents. b) Write out the loop rule for the left loop in the circuit. c) Write out the loop rule for the right loop in the circuit. d) Solve for the three currents. Report their directions with +signs ("+" = direction agrees with diagram). [+A] , [+A] , [+A] e) Find the potential difference: VA - VB. [V]
