Where V1 = 230 V, R1 = 22 2, R2 = 40 N, R3 = 59 N, R4 = 57 2, and R5 = 77 N, and a = 4 id. ia R1 R2 R5 id Fib V1 R3 Lie R4 Enter the values of the currents ia to ie ja = Number A ib = Number A ic = Number A id = Number A ie = Number A

Problem 2: Question 2. Consider the circuit diagram below. The circuit supplies power to the unknown resistive load, RL. a) Determine the value of the load that will result in maximum power transfer from the supply circuit to the load. b) Determine the value of the load that will result in 90% efficiency. c) Prove that your chosen load resistor in a) is allowing for maximum power transfer by plotting the power dissipated vs resistance for at least 6 load resistor values. Use CircuitJS to simulate the values for different load resistors. You do not have to submit anything from your simulations, but you do need to include your graph. The graph can be created by hand, Excel or Matlab. VT 75 V +₁₁ 33 ΚΩ www 41 ΚΩ 16 ΚΩ R₂
