Figure 1 shows an electrical circuit with a current source and four resistors. All the questions in this examination relate to this circuit. All the equations necessary for this exam

are given in the last page. The circuit has two essential nodes - one is a reference node as shown as ground in the figure and the other an unknown node with voltage, V1. Part 3 (k) Figure 5 shows that the optimum load resistor in part (i) is implemented using two parallel resistors, RL1 and RL2. RL1 is given figure 5. Find the value of RL2. (10)(m) For the case in part (k), find the power delivered to the two resistors, RL1 and R12. (10)
