8. Find the value of RL for maximum power for the network in Figure 8 and find the value of this power
A resistive load RL, of 10 Ω is connected between points A and B as illustrated in the following figure:
The load is supplied by two different DC power supplies with internal resistors known as R1 and R2. The voltage across the load should be maintained at 12V. You are asked to use electrical circuit theorems to determine the values of R1 and R2 to achieve the required voltage across the load.
Analyze the circuit below. Find the voltages V1 and V2. Find the currents I1 and I2.
(Utilize Phasors)
(Since there are two sources, you would also need to utilize superposition)
