Problem 7: In the circuit shown below, the current I1 on the left, EL = 48V, in the middle, Em = 12V, and on the right, ER= 20V, are given. The resistance Rx and the currents I2 and Iz are not given. +2.4A and the battery voltages In -w- b Rx 3. 20 V 48 V 12 V 4.2 Use the loop b – c – d – e – b to find the current I2. Then use the junction b or e to find the current 13. Does the current through the 6N resistor, |I2|, flow from c to b (= in I2-arrow direc does it flow from b to c (= opposite to I2-arrow direction)? on), or |3| Problem 8: Find the resistance R in the circuit described in Problem 7. Hint and Warning: Do not use the values of currents I2 and/or I3 you may have found in Problem 7! You do not need them! Rather, use only some values for the battery voltages and the value for the current I that are given in Problem 7. (A) R (B) R - 0.067 N (C) R (D) R. (E) R =144.0 N 0.040 N 15.0 N 25.0 N
