Task D & E - Please help me with these two tasks. Thank you!

(e) The circuit in task ((1) proved to be complex to analyse, therefore, Analyse Systems decided to create a version with a reduced number of resistors and see how that can affect the power dissipated in 40. load resistor. R1 =40 R2=20 V1=12V ' ' V2=8V RL=4D . Use an appropriate circuit theory to find the power dissipated in the load resistor RL. (d) It is your job now to evaluate the operation of the new circuit by applying the principles of circuit theory. To do this, you will need to answer the following: 1. To verify your ndings, use at least two different circuit theories to find the current owing in the 40 load resistor. 2. Comment on your results 3. Using any appropriate circuit theory, find the current owing in each of the other two branches of the circuit. 4. The power dissipated in the 40 load resistor R1 = 40 R2 =1.so v1 :12v - v2 =4v RL = 40 R3 = 20 R4 = 0.50
