(8%) Problem 9: Consider the circuit in the figure, with the current directions defined as shown. There are four resistors in this circuit (R, R, R3, and R4) and four batteries with emfs & = 15.5 V, &2 = 5.5 V, &3 = 9.5 V, and 4 = 21.8 V, each with internal resistance given by r; as marked in the figure. Randomized Variables &= 15.5 V &=5.5 V &3=9.5 V 4 = 21.8 V A 33% Part (a) Calculate the current 1 in amps. Calculate the current 13 in amps.
